    Case: 17-14052     Date Filed: 11/02/2018    Page: 2 of 20
    Before TJOFLAT, MARCUS, and NEWSOM, Circuit Judges.
    NEWSOM, Circuit Judge:
    You’ve undoubtedly heard of—and for that matter probably accepted the
    terms of—a “shrinkwrap” agreement, which binds a software (or small-electronics)
    purchaser to an inside-the-box contract if she opens the product and retains it for
    some specified time. In this cyber age, you’ve also almost certainly assented to the
    terms of a “clickwrap” or “scrollwrap” agreement—for instance, by hitting “I
    accept” when installing the latest operating system for your smartphone. This
    case—not quite as hip but governed by the same basic principles—requires us to
    determine the enforceability of what, for lack of a better label, we’ll call a
    “shinglewrap” agreement.
    Boiled to its essence, the question we must decide is this: Where a roofing-
    shingle manufacturer displays on the exterior wrapping of every package of
    shingles the entirety of its product-purchase agreement—including, as particularly
    relevant here, a mandatory-arbitration provision—are homeowners whose roofers
    ordered, opened, and installed the shingles bound by the agreement’s terms?
    Applying Florida law, we conclude that the homeowners are bound—and must
    therefore arbitrate any product-related claims that they allege against the
    manufacturer. In particular, we hold (1) that the manufacturer’s packaging here
    sufficed to convey a valid offer of contract terms, (2) that unwrapping and
    2
    Case: 17-14052      Date Filed: 11/02/2018    Page: 3 of 20
    retaining the shingles was an objectively reasonable means of accepting that offer,
    and (3) that the homeowners’ grant of express authority to their roofers to buy and
    install shingles necessarily included the act of accepting purchase terms on the
    homeowners’ behalf.
    I
    A
    Tamko Building Products is a Missouri-based roofing company. 1 Its
    “Heritage 30” shingles come with (appropriately) a 30-year limited warranty,
    which is printed—in full—on the outside wrapper of every shingle package.
    Although most of the warranty is set in ordinary Roman type, several key
    portions—including those most significant to this appeal—are rendered in a more
    conspicuous font. Each package wrapper, for instance, displays the all-capped
    word “IMPORTANT” and warns the purchaser—again in all caps—to “READ
    CAREFULLY BEFORE OPENING [THE] BUNDLE.” The wrapper further
    explains (1) that the consumer must notify Tamko of any warranty-related claims
    “within thirty (30) days following discovery of the problem with the Shingles” and
    (2) that the warranty and other purchase terms are available not only on the face of
    the wrapper itself but also on Tamko’s website and via a toll-free telephone
    number.
    1
    Although the company’s logo reads “TAMKO,” we use “Tamko” for the sake of readability.
    3
    Case: 17-14052       Date Filed: 11/02/2018       Page: 4 of 20
    As particularly relevant to this appeal, Tamko’s limited warranty contains a
    mandatory-arbitration clause—which, significantly, is also printed in its entirety,
    and in all caps, on the outside of every shingle wrapper. In pertinent part, that
    clause states as follows:
    MANDATORY BINDING ARBITRATION: EVERY CLAIM,
    CONTROVERSY, OR DISPUTE OF ANY KIND WHATSOEVER
    (EACH AN “ACTION”) BETWEEN YOU AND TAMKO
    (INCLUDING ANY OF TAMKO’S EMPLOYEES AND AGENTS)
    RELATING TO OR ARISING OUT OF THE PRODUCT SHALL
    BE RESOLVED BY FINAL AND BINDING ARBITRATION,
    REGARDLESS OF WHETHER THE ACTION SOUNDS IN
    WARRANTY, CONTRACT, STATUTE, OR ANY OTHER LEGAL
    OR EQUITABLE THEORY.
    The warranty further specifies that any action against Tamko must be arbitrated
    individually rather than as part of a consolidated or class action:
    ANY ACTION BROUGHT BY USE AGAINST TAMKO WILL BE
    ARBITRATED (OR, IF ARBITRATION OF THE ACTION IS NOT
    PERMITTED BY LAW, LITIGATED) INDIVIDUALLY AND YOU
    WILL NOT CONSOLIDATE, OR SEEK CLASS TREATMENT
    FOR, ANY ACTION UNLESS PREVIOUSLY AGREED TO IN
    WRITING BY BOTH TAMKO AND YOU. 2
    B
    Enter Douglas Bohn and Stephen Dye. Both are Florida residents whose
    homes are fitted with Tamko’s Heritage 30 shingles. Bohn hired Duffield Home
    2
    There are actually two wrappers, two purchase agreements, and two arbitration provisions in
    the record here. Although the language of the agreements and their associated arbitration
    provisions differs ever so slightly, they are materially identical.
    4
    Case: 17-14052     Date Filed: 11/02/2018   Page: 5 of 20
    Improvements to install a new roof on his Middleburg, Florida home. After a few
    years, he noticed that his shingles were crumbling and that asphalt granules were
    shedding and collecting in his gutters. Similarly, Dye hired Tampa Roofing
    Company to replace the roof on his house in Tampa, Florida. Shortly after
    installation, Dye too noticed his shingles cracking and granules littering his patio.
    Bohn and Dye filed a putative class action seeking damages and declaratory
    relief on behalf of a class of building owners who had used Tamko shingles. Their
    complaint alleged that Tamko manufactured its Heritage 30 shingles with less
    asphalt than necessary to comply with industry standards and building codes,
    which caused the shingles to crack and split. The complaint included claims for
    breach of express and implied warranties, strict products liability, negligence, and
    violations of the Florida Deceptive and Unfair Trade Practices Act. In response,
    Tamko filed a motion to compel arbitration and an accompanying motion to
    dismiss or stay court proceedings. Tamko contended that by unwrapping and
    retaining its shingles the homeowners had accepted the terms of its purchase
    agreement and were thus bound, pursuant to the agreement’s plain terms, to
    arbitrate their claims.
    The district court granted Tamko’s motion and dismissed the homeowners’
    complaint. The court reasoned that the homeowners were bound to arbitrate
    because through their roofers, whom they had hired to buy and install the shingles,
    5
    Case: 17-14052        Date Filed: 11/02/2018      Page: 6 of 20
    they had accepted the terms of Tamko’s purchase agreement, including its
    mandatory-arbitration provision. This appeal followed.
    II
    On appeal, we must determine whether Tamko’s warranty-emblazoned
    shingle wrappers set forth a valid offer that gave purchasers an adequate
    opportunity to assent to its terms—most notably, the mandatory-arbitration
    clause—and, if so, whether the roofers, as the homeowners’ agents for the
    purposes of purchasing and installing shingles, bound the homeowners to arbitrate
    by unwrapping the shingle packages. We consider each issue in turn.3
    A
    First up, we consider whether the shingle wrappers conveyed a valid offer of
    Tamko’s contract terms—in particular, that any product-related dispute must be
    arbitrated rather than litigated. Of course they did, Tamko says, asserting that the
    law is well-settled that opening and retaining a product constitutes acceptance of
    terms printed on the product’s packaging. The homeowners, by contrast, contend
    that consumers aren’t on notice that shingles come wrapped in purchase terms and
    can’t assent to terms of which they are unaware. The nub of the dispute is whether
    3
    We review de novo the district court’s order granting Tamko’s motion to dismiss and compel
    arbitration. Bodine v. Cook’s Pest Control Inc., 
    830 F.3d 1320
    , 1324 (11th Cir. 2016) (citation
    omitted).
    6
    Case: 17-14052       Date Filed: 11/02/2018        Page: 7 of 20
    Tamko’s shingle wrappers provide a reasonable opportunity for consumers to
    review and accept the company’s terms of purchase.
    Florida law provides the rules of decision here.4 Applying Florida law, we
    recently held that “[a] valid contract—premised on the parties’ requisite
    willingness to contract—may be ‘manifested through written or spoken words, or
    inferred in whole or in part from the parties’ conduct.’” Kolodziej v. Mason, 
    774 F.3d 736
    , 741 (11th Cir. 2014) (quoting L & H Constr. Co. v. Circle Redmont, Inc.,
    
    55 So. 3d 630
    , 634 (Fla. 5th Dist. Ct. App. 2011)); see also 
    Fla. Stat. § 672.204
    (1)
    (“A contract for sale of goods may be made in any manner sufficient to show
    agreement, including conduct by both parties which recognizes the existence of
    such a contract.”). Somewhat more specifically, courts applying Florida law have
    clarified (1) that “[a] vendor, as master of the offer,” is free to “invite acceptance
    by conduct” and in so doing to “propose limitations on the kind of conduct that
    constitutes acceptance,” and (2) that a consumer may, in turn, “accept by
    performing the acts the vendor proposes to treat as acceptance.” TracFone
    Wireless, Inc. v. Pak China Grp. Co., 
    843 F. Supp. 2d 1284
    , 1298 (S.D. Fla. 2012)

    Although the Federal Arbitration Act embodies an “emphatic federal policy in favor of arbitral
    dispute resolution,” KPMG LLP v. Cocchi, 
    565 U.S. 18
    , 21 (2011), this policy does not apply to
    the threshold question of whether there is “a valid agreement to arbitrate between the parties.”

    622 F.3d 1335
    , 1342 (11th Cir. 2010) (quotations omitted). That question is governed instead by
    the “ordinary state-law principles that govern the formation of contracts.” Bazemore v. Jefferson
    Capital Sys., LLC, 
    827 F.3d 1325
    , 1329 (11th Cir. 2016) (quoting First Options of Chi., Inc. v.
    Kaplan, 
    514 U.S. 938
    , 944 (1995)).
    7
    Case: 17-14052      Date Filed: 11/02/2018   Page: 8 of 20
    (quotations omitted); accord, e.g., Salco Distribs., LLC v. iCode, Inc., No. 8:05–
    CV–642, 
    2006 WL 449156
    , at *2 & n.5 (M.D. Fla. Feb. 22, 2006) (quoting
    ProCD, Inc. v. Zeidenberg, 
    86 F.3d 1447
    , 1449 (7th Cir. 1996)).
    These settled principles give rise to two fundamental inquiries: (1) Would “a
    reasonable, objective person” have understood an offer as an “invitation to
    contract,” and (2) did that person’s “words and acts, judged by a reasonable
    standard, manifest an intention to agree?” Kolodziej, 774 F.3d. at 741–42
    (quotation omitted). In considering these questions, a court must examine the
    content of the offer, the circumstances in which the offer was made, and the
    conduct of the parties—all the while keeping firmly in mind that “[t]he law
    imputes to a person an intention corresponding to the reasonable meaning of his
    words and acts.” Id. at 742 (quoting Lucy v. Zehmer, 
    84 S.E.2d 516
    , 522 (Va.
    1954), “the classic case describing and applying what we now know as the
    objective standard of assent”).
    As particularly relevant here, courts applying Florida law have recognized
    that a vendor’s prerogative to specify conduct that constitutes acceptance includes
    inviting acceptance by unwrapping a product. Take, for instance, TracFone
    Wireless, Inc. v. Pak China Group Co. Ltd., a shrinkwrap case cited extensively by
    both parties. There, a cellphone manufacturer’s retail packaging displayed
    “conspicuous language” specifically “restricting the use of the Phones for
    8
    Case: 17-14052     Date Filed: 11/02/2018   Page: 9 of 20
    TracFone Prepaid Wireless service and prohibit[ing] the consumer from tampering
    or altering the software or hardware in the Phone.” TracFone, 843 F. Supp. 2d at
    1298. The language further stated that “[b]y purchasing or opening this package”
    the consumer agreed to the manufacturer’s terms as printed on the wrapper and in
    the enclosed user guide. Id. Applying Florida law, the court held that a
    consumer’s act of opening the package constituted an acceptance of the
    manufacturer’s terms, thereby creating a valid contract. Id. at 1298–99.
    Management Computer Controls, Inc. v. Charles Perry Construction, Inc., 
    743 So. 2d 627
     (Fla. 1st Dist. Ct. App. 1999), is similar. There, a computer-software
    vendor sent a product to a customer with its licensing agreement affixed to the
    outside of the box, which was itself sealed with an orange sticker warning that
    “[b]y opening this packet, you indicate your acceptance of the [company’s] license
    agreement.” 
    Id. at 629
    . The court deemed this a valid offer and held that the
    consumer “agreed to the terms of the license agreement by breaking the seal on the
    software.” 
    Id. at 631
    .
    This case is cut from the same cloth. Tamko’s purchase terms were printed
    in full on the exterior of every package of shingles, accompanied by text alerting
    purchasers of an “IMPORTANT” message that they should “READ CAREFULLY
    BEFORE OPENING [THE] BUNDLE.” The agreement required consumers to
    notify Tamko “within thirty (30) days following discovery of the potential problem
    9
    Case: 17-14052        Date Filed: 11/02/2018        Page: 10 of 20
    with the Shingles,” and further—most importantly here—featured an all-caps,
    mandatory-arbitration clause.5 As in the shrinkwrap cases, Tamko’s packaging
    provided conspicuous notice of its offer—something a reasonable, objective person
    would understand as an invitation to contract. See Kolodziej, 774 F.3d at 741. For
    the homeowners’ part, opening and retaining the shingles was the (quite ordinary,
    reasonable) conduct from which their assent can be “inferred.” See id.
    The homeowners acknowledge that Florida law recognizes “shrinkwrap”
    contracting but contend that the nature of the product here calls for a different
    analysis. It’s a fair point. Software packaging of the sort typically involved in a
    shrinkwrap case is fairly small, usually delivered directly to (and sometimes
    retained by) the end user, and often includes at least some notice of terms printed
    both on the outside and inside of the package. By contrast, shingle packages are
    large and unwieldy, are often delivered to contractors rather than end users, are
    quite unlikely to be kept following installation, and in this case sported terms
    5
    The homeowners assert, for the first time on appeal, that this Court needn’t reach the issue of
    assent (or agency, see infra) because Tamko failed to provide the district court sufficient
    evidence of its shingle wrapper, leaving the court unable to evaluate whether the purchase terms
    were conspicuous enough to provide sufficient notice of the offer. In particular, the homeowners
    contend that a Tamko employee’s affidavit, which describes and reproduces the purchase
    agreement—including the arbitration provision—isn’t good enough, and that either an actual
    shingle wrapper or a photograph was necessary. The homeowners did not, however, dispute the
    sufficiency (or form) of the evidence in the district court, but rather have been arguing the merits
    of assent (and agency) all along. Absent special circumstances, which we conclude do not exist
    here, we will not address an argument raised for the first time on appeal. See Access Now, Inc. v.
    Sw. Airlines Co., 
    385 F.3d 1324
    , 1335 (11th Cir. 2004).
    10
    Case: 17-14052     Date Filed: 11/02/2018    Page: 11 of 20
    printed only once on the outer wrapping. These differences matter, the argument
    presumably goes, because Florida law tasks courts with determining whether “a
    reasonable, objective person” would have understood Tamko’s packaging as “an
    invitation to contract.” Kolodziej, 774 F.3d at 741. And it’s just not clear that
    consumers have the same realistic opportunity to review shingle (or floorboard,
    siding, or tile) packaging as they would software packaging.
    To be sure, there are distinctions between small-box and big-box items, but
    those distinctions neither alter the underlying principles nor require a different
    result. Indeed, they arguably cut in different ways. On the one hand, for instance,
    it’s surely true that a consumer (or his agent—more on that below) is less likely to
    keep shingle packaging than software packaging after unwrapping the product. On
    the other hand, one of the things that has historically made shrinkwrap cases tricky
    is that the full purchase terms “are typically provided inside the packaging of
    consumer goods,” while the outer packaging bears only a notice or excerpt of those
    terms—leading courts to hold that valid acceptance occurs not upon purchase or
    opening, but rather only upon the purchaser’s “failure to return the product after
    reading, or at least having a realistic opportunity to read, the terms and conditions
    of the contract included with the product.” Schnabel v. Trilegiant Corp., 
    697 F.3d 11
    Case: 17-14052       Date Filed: 11/02/2018       Page: 12 of 20
    110, 121–22 (2d Cir. 2012) (emphasis added).6 Here, by contrast—in the
    quintessential belt-and-suspenders move—Tamko has emblazoned its entire
    purchase-agreement (complete with terms, warnings, and the all-important
    arbitration clause) in haec verba on the outside of every package of shingles. No
    hidden terms—no buried treasure.
    Moreover, and in any event, that big-box items come with purchase terms
    and conditions should hardly come as a surprise to modern consumers. Post-
    purchase, acceptance-by-retention warranties are ubiquitous today—think
    furniture, home appliances, sporting goods, etc. It’s not only objectively
    reasonable to assume that such items come with terms and conditions, it’s also
    eminently reasonable to assume that by opening and retaining those items a
    consumer necessarily accepts the accompanying terms and conditions. See
    Kolodziej, 774 F.3d at 742 (“[T]he law imputes to a person an intention
    6
    While shrinkwrap cases generally consist of “[n]otice on the outside, terms on the inside, and a
    right to return the software for a refund if the terms are unacceptable,” Nicosia v. Amazon.com,
    Inc., 
    834 F.3d 220
    , 232 (2d Cir. 2016) (quotation omitted), in some instances shrinkwrap offers
    further require consumers to click “accept” upon installing the software itself, see, e.g.,
    Register.com, Inc. v. Verio, Inc., 
    356 F.3d 393
    , 428 (2d Cir. 2004) (characterizing shrinkwrap
    licenses as involving (1) “notice of a license agreement on product packaging,” (2) “presentation
    of the full license on documents inside the package,” and (3) “prohibited access to the product
    without an express indication of acceptance”); ProCD, 
    86 F.3d at
    1450–53 (requiring consumer
    to click a button indicating acceptance of terms during software installation, in addition to
    providing notice on the box and terms inside the box). And in still other shrinkwrap cases, terms
    are printed in full on the exterior of the packaging, as in the case before us today. See, e.g.,
    Mgmt. Comput. Controls, 
    743 So. 2d at 629
     (licensing agreement affixed to outside of the box,
    which was also sealed with an orange “notice” sticker).
    12
    Case: 17-14052     Date Filed: 11/02/2018    Page: 13 of 20
    corresponding to the reasonable meaning of his words and acts.” (quotations
    omitted)).
    Indeed, this expectation—and with it, fair notice—has been building for
    some time. More than 20 years ago, in Hill v. Gateway 2000, 
    105 F.3d 1147
     (7th
    Cir. 1997), the Seventh Circuit rejected a suggestion that its earlier decision in
    ProCD, Inc. v. Zeidenberg, 
    86 F.3d 1447
     (7th Cir. 1996)—the seminal case on
    shrinkwrap contracts—applied only to software, for precisely this reason. See Hill,
    
    105 F.3d at 1149
     (“ProCD is about the law of contract, not the law of software.”).
    The Hill court explained that “[p]ractical considerations support allowing vendors
    to enclose the full legal terms with their products,” employing a “simple approve-
    or-return” model in place of a “costly and ineffectual” requirement that sellers
    narrate their terms of purchase “telephonic[ally].” 
    Id.
     When it comes to
    warranties and other purchase terms, the Hill court explained, “[c]ompetent adults
    are bound by such documents, read or unread.” Id; see also 
    id. at 1148
     (“A
    contract need not be read to be effective; people who accept [the contract] take the
    risk that the unread terms may in retrospect prove unwelcome.”).
    All of that applies a fortiori two decades hence, in the age of Amazon Prime.
    As fewer and fewer purchases are consummated face to face, and more and more
    are made online, consumers should (and must) know that vendors will often
    employ a “simple approve-or-return” model, enclosing their full legal terms with a
    13
    Case: 17-14052       Date Filed: 11/02/2018      Page: 14 of 20
    product at shipment. Indeed, the sort of “costly and ineffectual” telephonic
    recitation of terms that the Hill court posited is a vanishingly small exception to the
    norm. 7 Really, how often does the modern consumer, following a large purchase,
    call a vendor to sit through a verbal oration of warranty terms? Or insist on
    signing and returning a form to convey acceptance of her latest online purchase,
    instead of just, oh, say, keeping it?
    That’s not to imply that consumers can’t choose to seek out purchase terms
    by other means should they so choose. Indeed, one key reason that the Hill court
    rejected the “I-didn’t-read-it” excuse was that consumers could discover the terms
    of their desired purchases in one of several ways, such as by “ask[ing] the vendor
    to send a copy before deciding whether to buy,” by “consult[ing] public sources
    (computer magazines, the Web sites of vendors),” or by “inspect[ing] the
    documents after the product’s delivery.” 
    105 F.3d at 1150
    . And of course, as we
    have emphasized, the same is true here—Tamko’s purchase terms were available
    not only on its packaging but also on its website and over the phone, such that a
    diligent consumer could easily have discovered and reviewed them before or after
    purchase.
    7
    So much so that the author of today’s opinion doesn’t even know what the Seventh Circuit was
    talking about. A “telephonic recitation” of warranty terms?
    14
    Case: 17-14052       Date Filed: 11/02/2018       Page: 15 of 20
    At the end of the day, the point is simply this: modern consumers are on
    notice that products come with warranties and other terms and conditions of
    purchase. And they are free to research (or not), request (or not), and read (or not)
    those terms before unwrapping their purchases. As to the case before us, Florida
    law makes clear that providing conspicuously printed product packaging is an OK
    way to convey purchase terms. Florida consumers who purchase, open, and retain
    a product are thus bound in accordance with warranty terms conspicuously printed
    on that product’s packaging, whether they actually take the time to read them or
    not. 8
    We can summarize using what this Court has referred to as the “million-
    dollar question” in evaluating assent: “What did the part[ies] say and do?”
    Kolodziej, 774 F.3d at 743. By conspicuously printing its purchase terms on its
    shingle wrappers, Tamko made a valid offer in accordance with Florida law. As
    master of that offer, Tamko was free to invite acceptance by specified conduct, and
    it did—inviting consumers to accept by opening the shingles and retaining them
    for more than 30 days. By doing exactly this, the homeowners here “accept[ed] by
    8
    This accords with the basic proposition—embraced by Florida courts—that “one who signs a
    written instrument without reading it with care” is, in most cases, “bound in accordance with its
    written terms.” All Fla. Sur. Co. v. Coker, 
    88 So. 2d 508
    , 510 (Fla. 1956). Although this appeal
    concerns unwrapping rather than signing, the principle holds true. See Hill,

    remember or understand it”).

    performing” the acts that Tamko “propose[d] to treat as acceptance,” thus
    “manifest[ing] an intention to agree.” TracFone, 843 F. Supp. 2d at 1298;
    Kolodziej, 774 F.3d at 742. We therefore hold that Tamko made a valid offer—
    again, including an offer to arbitrate, rather than litigate, all product-related
    claims—and that its offer was accepted.
    B
    Hang on just a minute, the homeowners contend: Even if this was a valid
    means of making an offer, they didn’t accept it—their roofers did. After all, the
    homeowners say, they never saw the shingle packaging and thus never had a
    reasonable opportunity to consider Tamko’s purchase terms—arbitration clause
    included—so they can’t possibly be bound by them. Attributing the roofers’
    acceptance to them would be, the homeowners assert, an “ill-advised” and
    “unsupported” expansion of agency law. We disagree. Imputing the roofers’
    notice and acceptance of Tamko’s purchase terms to the homeowners requires no
    expansion, but rather fits squarely within established agency-law principles and
    precedent.
    Let’s start with the basics. “[A]n agency relationship requires (1) the
    principal to acknowledge that the agent will act for it; (2) the agent to manifest an
    acceptance of the undertaking; and (3) control by the principal over the actions of
    the agent.’” Franza v. Royal Caribbean Cruises, Ltd., 
    772 F.3d 1225
    , 1236 (11th

    Cir. 2014) (quotation omitted). Importantly here, we have further held—applying
    Florida law—that a grant of agency authority also necessarily implies “the
    authority to do acts that are ‘incidental to it, usually accompany it, or are
    reasonably necessary to accomplish it.’” Bd. of Trs. of City of Delray Beach Police
    & Firefighters Ret. Sys. v. Citigroup Glob. Mkts., Inc., 
    622 F.3d 1335
    , 1342–43
    (11th Cir. 2010) (quoting 2 Fla. Jur.2d Agency & Employment § 47 (2005)).9 As
    examples of this “incidental-to” authority, Florida courts have held, for example,
    that real-estate agents charged with selling property have authority to purchase
    surveying services on behalf of their principals, Bradley v. Waldrop, 
    611 So. 2d 31
    , 32–33 (Fla. 1st Dist. Ct. App. 1992), and “to make representations concerning
    the description and characteristics of the property to be sold,” Outlaw v.
    McMichael, 
    397 So. 2d 1009
    , 1010 (Fla. 1st Dist. Ct. App. 1981).
    This case is similar. Neither party seriously disputes that the roofers were
    the homeowners’ agents for purposes of purchasing and installing shingles. Both
    homeowners expressly delegated those tasks to their roofers, their roofers accepted
    those tasks by signing contracts, and the homeowners maintained control over their
    roofers’ completion of those tasks pursuant to those contracts. See Franza, 772
    9
    See also Restatement (Third) of Agency § 2.02 cmt. d (Am. Law. Inst. 2006) (“If a principal’s
    manifestation to an agent expresses the principal’s wish that something be done, it is natural to
    assume that the principal wishes, as an incidental matter, that the agent take the steps necessary
    and . . . proceed in the usual and ordinary way[.]”).

    F.3d at 1236. The question, then, is whether accepting Tamko’s purchase terms—
    including an arbitration provision—was “incidental to,” “usually accompany[ing],”
    or “reasonably necessary to accomplish” the purchase and installation of the
    shingles. See Delray Beach, 
    622 F.3d at
    1342–43.
    The homeowners admit that they contracted with their roofers to buy
    shingles, and even that the roofers might have known that by opening the shingles,
    they—i.e., the roofers—were entering into an agreement with Tamko. But the
    homeowners dispute that this necessarily means that the roofers accepted Tamko’s
    purchase terms—including, as we keep saying, the arbitration clause—on the
    homeowners’ behalf. Had they made clear that their roofers could enter into
    binding contracts on their behalf, the homeowners contend, that grant might have
    encompassed agreeing to the arbitration provision. But, they say, a “circumscribed
    contract . . . to buy and install shingles does not bring with it the authority to enter
    into any other contract whatsoever regarding those shingles.”
    We think the homeowners are missing the point. Accepting the purchase
    terms is not “any other contract . . . regarding those shingles”—it is the contract
    regarding those shingles. Purchasing a product necessarily and by definition
    encompasses accepting the terms of that purchase. The homeowners here
    expressly delegated to their roofers the task of purchasing shingles, and yet they
    now contest terms—in particular, those requiring mandatory arbitration—that are
    18
    Case: 17-14052       Date Filed: 11/02/2018       Page: 19 of 20
    part and parcel of that purchase. In the language of our precedent, accepting
    purchase terms is “incidental to,” “usually accompany[ing],” and “reasonably
    necessary to” the act of purchasing. And Florida law is clear that, in this respect at
    least, arbitration terms are no different from any others: “[A]n agent can bind
    a principal to an arbitration agreement just like any other contract.” Fi–Evergreen
    Woods, LLC v. Estate of Robinson, 
    172 So. 3d 493
    , 497 (Fla. 5th Dist. Ct. App.
    2015). 10
    Even aside from our “incidental-to” precedent, it is axiomatic under Florida
    law—and more generally—that knowledge or notice that an agent acquires while
    acting within the course and scope of his authority is generally imputed to his
    principal. See, e.g., Chang v. JPMorgan Chase Bank, N.A., 
    845 F.3d 1087
    , 1095
    (11th Cir. 2017); Restatement (Third) Of Agency § 5.03 (“For purposes of
    determining a principal’s legal relations with a third party, notice of a fact that an
    agent knows or has reason to know is imputed to the principal if knowledge of the
    fact is material to the agent’s duties to the principal[.]”). Here, Tamko’s purchase
    terms were printed on the shingle packaging, which the homeowners agree their
    10
    To the extent that the homeowners argue that their roofers may bind them to some purchase
    terms, but not those pertaining to arbitration, the contention is foreclosed by recent Supreme
    Court precedent. See Kindred Nursing Ctrs. Ltd. P’ship v. Clark, 
    137 S. Ct. 1421
    , 1425 (2017)
    (confirming that arbitration agreements may not be singled out for unfavorable treatment); see
    also Fi–Evergreen Woods, 
    172 So. 3d at 497
     (“There is no special rule requiring the principal to
    independently waive the right to a jury trial or expressly and separately acknowledge or agree
    that the agent is also authorized to waive a jury trial on his or her behalf.”).

    roofers opened. Because the notice that their roofers acquired while acting within
    the scope of their authority to purchase and install the shingles is properly imputed
    to them, the homeowners cannot now plead ignorance of the offer’s existence.
    To summarize, then, acceptance of Tamko’s purchase terms—arbitration
    clause and all—was incidental to, and reasonably necessary to accomplish, the
    homeowners’ express grant of agency authority to their roofers to purchase and
    install shingles, and in any event, the roofers’ notice of the terms printed on the
    shingle wrappers is properly imputed to the homeowners.
    III
    As “master of the offer,” Tamko invited purchasers to accept its contract
    terms by opening and retaining the shingles—a reasonable means of acceptance-
    by-conduct under Florida law. The homeowners, through their roofer agents,
    validly accepted those terms—Tamko’s binding arbitration provision included.
    We therefore affirm the district court’s decision to grant Tamko’s motion to
    compel arbitration and to dismiss the homeowners’ complaint.
    AFFIRMED.
