    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    JUSTICE LOPEZ, Opinion of the Court:
    ¶1            The United States District Court for the District of Arizona
    certified two questions for our review: (1) Does an effective modification of
    a consumer contract occur when the offeror sends notice of the proposed
    modification to the offeree, through a communication channel to which the
    offeree previously consented, even if the offeree fails to respond?; and (2) If
    not, what additional showings (such as actual receipt of the notice of
    proposed modification, subjective understanding of the proposed
    modification, or affirmative consent to the proposed modification) are
    necessary to achieve an effective contract modification in this circumstance?
    ¶2             We hold that on-going, at-will, consumer-business
    relationships consist of the day-to-day offer and acceptance of unilateral
    contracts; thus, businesses may effectively modify the non-negotiated,
    standardized terms governing these relationships if the business
    demonstrates that (1) the contract’s initial terms expressly notified the
    consumer that the business could make future changes to the terms; (2) the
    business gave—and the consumer received—reasonable notice of the
    modification and an opportunity to opt out with no change to the status
    quo business relationship; and (3) the consumer continued the business
    relationship past a reasonable opt-out period. In so holding, we adopt the
    Restatement of Consumer Contracts § 3 (Am. L. Inst., Tentative Draft No. 2,
    2022) (“Restatement § 3”) to the extent our previous holding in Darner
    Motor Sales v. Universal Underwriters Insurance Co., 
    140 Ariz. 383
     (1984), does
    not provide for this result. Our answer to the first question in the
    affirmative obviates the need to address the second question.
    BACKGROUND
    ¶3            In October 2018, as a part of opening checking and savings
    accounts with Desert Financial, Eva Cornell agreed to certain terms and
    conditions (the “Terms”). These stated that Desert Financial could “change
    those terms and conditions from time to time.” Cornell also “consented to
    the electronic delivery of all future communications from Desert Financial,
    including all disclosures, notices, and account statements.” At that time,
    the Terms did not contain an arbitration clause.
    ¶4          When Cornell agreed to the Terms, she was subjectively
    unaware of the absence or presence of an arbitration clause. In a later
    2
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    deposition, she testified that even had the Terms originally included an
    arbitration clause, and she knew of the clause, she would have still agreed
    to the Terms.
    ¶5            In February 2021, Desert Financial updated its Terms, adding
    a mandatory arbitration clause. The clause appeared on page five of a
    fourteen-page document and began as follows: “DISPUTE RESOLUTION:
    MANDATORY             ARBITRATION.        READ      THIS      PROVISION
    CAREFULLY AS IT WILL HAVE A SUBSTANTIAL IMPACT ON HOW
    LEGAL CLAIMS YOU AND THE CREDIT UNION HAVE AGAINST
    EACH OTHER WILL BE RESOLVED.” The following text explained that
    “[a]rbitration is not a mandatory condition of you maintaining an account
    with Credit Union” and that “YOU MAY OPT OUT of this arbitration
    provision so long as the Credit Union receives notice of your desire to opt-
    out by April 30, 2021 or 30 days after you open your account, whichever is
    later.” The clause also explained how to opt out.
    ¶6            Desert Financial did not directly contact its account holders
    concerning its updated Terms. Rather, it posted on monthly account
    statements a contrasting orange-and-blue banner stating in large block
    lettering: “Change-in-Terms.” In much smaller font, the banner informed
    readers that the changes concerned “how we will resolve legal disputes
    related to your accounts.” At the banner’s bottom, it directed readers to
    view the complete and updated version of the Terms by clicking on a
    provided URL written in bold font typical to hyperlinks.
    ¶7            Because Cornell opted for electronic communications, she did
    not receive account statements in the mail. On March 23, 2021, Desert
    Financial notified her that her March account statement was available for
    online viewing.     The “Change-in-Terms” banner appeared on the
    statement, which she could access any time she signed into her account.
    ¶8            On April 13, 2021, in conjunction with her efforts to buy a car,
    Cornell used Desert Financial’s mobile app to download a PDF of her
    monthly account statement for March 2021. During the downloading
    process, she saw the “Change-in-Terms” banner appearing on the
    statement. Later, when she was unable to locate her downloaded PDF, she
    again saw the banner when she obtained an electronic copy of the March
    2021 statement from Desert Financial via DocuSign. Ultimately, she never
    clicked the banner’s URL, viewed the updated Terms, or took the
    prescribed steps for affirmatively opting out of the arbitration clause.
    3
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    ¶9           On May 5, 2021, Cornell filed a class action suit in the District
    of Arizona, alleging “ambiguous and misleading language” concerning
    overdraft fees in violation of federal law. In response, Desert Financial
    moved to compel arbitration, arguing that the February 2021 arbitration
    clause became part of its Terms binding on Cornell. Cornell argued that
    she never assented to the updated Terms; thus, the arbitration clause was
    never incorporated into her agreement with Desert Financial.
    ¶10            On October 8, 2021, the district court ordered supplemental
    briefing on whether Cornell’s continued patronage following Desert
    Financial’s amendment and notice via the orange-and-blue banner
    constitutes “a valid contract modification under Arizona law.” Following
    a hearing and review of the parties’ briefing, on March 11, 2022, the district
    court certified to this Court two questions concerning contract
    modification. Because Arizona law is unclear concerning the requirements
    for unilateral modification of standard consumer contracts, we agreed to
    provide clarification pursuant to our jurisdiction under article 6,
    section 5(6) of the Arizona Constitution and A.R.S. § 12-1861.
    DISCUSSION
    ¶11           In considering the requirements for modifying the terms of
    at-will, on-going, business-consumer relationships, we conclude that our
    jurisprudence does not provide definitive guidance. To fill this void, we
    adopt Restatement § 3 because it is consistent with Arizona contract law
    and sets forth sound public policy.
    I.
    A.
    ¶12            We begin with fundamental Arizona contract law, which
    distinguishes between bilateral contracts and unilateral contracts. Knack v.
    Indus. Comm’n, 
    108 Ariz. 545
    , 548 (1972). Bilateral contracts consist of an
    exchange of promises. Id.; Wagner v. City of Globe, 
    150 Ariz. 82
    , 85 (1986)
    (“[B]ilateral contract[s] . . . require mutuality of obligation . . . .”). Once a
    bilateral contract is formed, its terms cannot be modified absent an
    additional offer, acceptance, and consideration. Demasse v. ITT Corp.,
    
    194 Ariz. 500
    , 506 ¶ 18 (1999).
    ¶13          In contrast, unilateral contracts are formed upon the offeree’s
    acceptance by performance. 
    Id.
     at 515 ¶ 53 (Jones, V.C.J., concurring in part
    4
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    and dissenting in part) (describing unilateral contracts as the “performance
    of an act in exchange for a promise to pay”). Before performance is
    rendered, the doctrine of contract modification does not apply to offers of
    unilateral contracts because there is no contract to modify, as shown in the
    at-will employment context:
    At-will employment contracts are unilateral and typically
    start with an employer’s offer of a wage in exchange for work
    performed; subsequent performance by the employee
    provides consideration to create the contract. Thus, before
    performance is rendered, the offer can be modified by the
    employer’s unilateral withdrawal of the old offer and
    substitution of a new one: the employer makes a new offer
    with different terms and the employee again accepts the new
    offer by performance (such as continued employment). Thus
    a new unilateral contract is formed—a day’s work for a day’s
    wages.
    
    Id.
     at 504–05 ¶ 12 (internal citations omitted). In this scenario, the next day’s
    unilateral contract offer’s terms may be changed at any time before
    performance. Id.; accord Wagner, 
    150 Ariz. at
    85–86; see also Johnson v.
    Associated Milk Producers, Inc., 
    886 N.W.2d 384
    , 392 (Iowa 2016) (“In an at-
    will contract, a party who gives notice of a changed term effectively offers
    a new contract in place of the existing one, which the other party may accept
    by continued performance.”).
    ¶14            Applying this at-will contract modification doctrine, the
    Alabama Supreme Court held that at-will bank patrons “implicitly assented
    to be bound by [new] arbitration provisions by holding open their accounts
    after notice of the amendment.” SouthTrust Bank v. Williams, 
    775 So. 2d 184
    ,
    191 (Ala. 2000). The court reasoned that “[a]mendments to the conditions
    of unilateral-contract relationships with notice of the changed conditions
    are not inconsistent with the general law of contracts.” 
    Id.
     at 190–91.
    ¶15           Conversely, a bilateral employment contract’s terms may
    only be modified with an offer, acceptance, and consideration. Demasse,
    
    194 Ariz. at
    506 ¶ 18. In proving acceptance, the employer carries the
    burden to show that the employee (1) received “legally adequate notice,”
    which is “more than the employee’s awareness of or receipt of the newest
    [employee] handbook,” 
    id.
     at 508 ¶ 24; and (2) “assented with knowledge
    of the attempted modification and understanding of its impact on the
    underlying contract,” id. ¶ 23.
    5
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    ¶16           In Demasse, this Court answered a certified question
    concerning employment contract modification. Id. at 502 ¶ 2. The initial
    terms of the case’s particular contract did not expressly allow unilateral
    changes to the terms, id. at 503 ¶¶ 4, 6, and for purposes of answering the
    certified question, we assumed that the contract was bilateral. Id. ¶ 5 n.1.
    Accordingly, we treated the inclusion of a reverse-seniority layoff provision
    to the contract as creating an implied-in-fact, bilateral, contractual term. Id.
    at 503 ¶ 5, 504 ¶ 11. We reasoned that, by creating job security, the
    provision “substantively govern[ed] the employee’s job and employment
    expectations”; thus, “‘the employer should reasonably have expected the
    employee to consider [the provision] as a commitment from the employer,’”
    as required for implied-in-fact employment contracts. Id. at 505 ¶ 16
    (quoting Soderlun v. Pub. Serv. Co., 
    944 P.2d 616
    , 621 (Colo. App. 1997)).
    Ultimately, we found ineffective the employer’s unilateral attempt to
    modify the bilateral contract’s reverse-seniority layoff term. 
    Id.
     at 507 ¶ 21,
    508 ¶¶ 24–25.
    ¶17           Cornell cites federal court rulings, 1 arguing that Demasse’s
    stringent modification rule applies to her and Desert Financial’s at-will
    banking deposit agreement. We disagree. Cornell and Desert Financial’s
    business relationship consists of day-to-day unilateral contract offers and
    acceptances. Like the at-will bank patrons in SouthTrust Bank, Cornell was
    free to terminate her accounts with Desert Financial at any time and vice
    versa. This materially differs from Demasse, where we considered the
    1 Rose v. Humana Ins. Co., No. CV-17-08107-PCT-DGC, 
    2018 WL 888982
    , at *3
    (D. Ariz. Feb. 14, 2018) (holding that an insurer’s email failed to modify an
    agreement because “even if . . . [the insurer’s] evidence of sending the email
    is accepted as true . . . [i]t does not show that [the insured] read . . . [or]
    understood the email and assented to the arbitration agreement it
    contained”); Vantage Mobility Int’l LLC v. Kersey Mobility LLC, No. CV-19-
    04684-PHX-JJT, 
    2021 WL 1610229
    , at *15–16 (D. Ariz. Apr. 26, 2021)
    (holding that a car dealer’s continued business with a supplier did not
    amount to acceptance of the supplier’s e-mailed offer to modify their
    existing agreement where the original agreement contained no unilateral
    modification clause, reasoning that “the daily business of sales did not
    implicate the terms of [the proposed modification],” and “[the supplier]
    produced no evidence that . . . gave [the dealer] reason to understand that
    [the dealer’s] assent could be manifested as silence or inaction”).
    6
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    modification of a bilateral employment contract whose original terms did
    not expressly provide for unilateral modification. Demasse does not
    articulate the applicable rule for altering the terms of at-will, on-going,
    consumer-business relationships. 
    194 Ariz. at
    504 ¶ 11 (describing the
    difference between at-will agreements and bilateral agreements as
    “dispositive with regard to methods necessary for modification”); Taleb v.
    AutoNation USA Corp., No. CV-06-02013-PHX-NVW, 
    2006 WL 3716922
    ,
    at *5 (D. Ariz. Nov. 13, 2006) (“The holding of the Arizona Supreme Court
    in [Demasse] is limited to situations in which an employer attempts to
    unilaterally modify a contract that creates an expectation of job
    security . . . .”).
    B.
    ¶18           Of our precedents, our decision in Darner comes closest to
    stating the applicable rule. In Darner, we held that courts may construe
    standardized agreements to reflect oral assurances made during
    negotiations even where the contract’s unambiguous, boiler plate language
    directly conflicts with the assurances. 
    140 Ariz. at
    395–96. We reasoned
    that although standardized contracts are integral to sustaining the sheer
    volume of daily transactions in modern society, customers entering
    standardized agreements do not often read or fully digest them, 
    id.
    at 393–94; thus, customers “are not bound to unknown terms which are
    beyond the range of reasonable expectation,” 
    id. at 391
     (quoting
    Restatement (Second) of Contracts § 211 cmt. f (Am. L. Inst. 1981)).
    ¶19            In so holding, we adopted the Restatement (Second) § 211,
    which recognizes that a term is unenforceable if “the other party has reason
    to believe that the party manifesting such assent would not do so if he knew
    that the writing contained a particular term.” Id. at 391 (quoting
    Restatement (Second) § 211). We further embraced Restatement (Second)
    § 211’s guidance concerning indicia of unenforceability of contract
    modifications:
    Such a belief or assumption may be shown by the prior
    negotiations or inferred from the circumstances. Reason to
    believe may be inferred from the fact that the term is bizarre
    or oppressive, from the fact that it eviscerates the non-
    standard terms explicitly agreed to, or from the fact that it
    eliminates the dominant purpose of the transaction. The
    inference is reinforced if the adhering party never had an
    opportunity to read the term, or if it is illegible or otherwise
    hidden from view. This rule is closely related to the policy
    7
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    against unconscionable terms and the rule of interpretation
    against the draftsman.
    Id. at 392 (quoting Restatement (Second) § 211 cmt. f).
    ¶20            Synthesizing unilateral contract law with Darner, an at-will
    consumer’s continued patronage (i.e., performance of the next day’s
    unilateral contract) constitutes valid acceptance of the business’s new terms
    if the consumer knew of the new terms when performing, see Demasse,
    
    194 Ariz. at
    504–05 ¶ 12, but the consumer cannot be bound by “unknown
    terms . . . beyond the range of reasonable expectation, ” Darner, 
    140 Ariz. at 391
     (quoting Restatement (Second) § 211 cmt. f). For example, for the
    Terms to be enforceable against Cornell, Desert Financial objectively must
    have had no reason to believe that she would not have accepted the Terms
    “if [she] knew that the writing contained a particular term.” Id. (quoting
    Restatement (Second) § 211).
    ¶21            Although this standard establishes the proper analytical
    framework, it fails to resolve whether enforceability requires the
    consumer’s actual knowledge of new terms, an issue that has divided
    courts. Compare Cap. One Bank v. Davey, No. 1 CA-CV 13-0109, 
    2013 WL 6729261
    , at *5 ¶ 20 (Ariz. App. Dec. 19, 2013) (mem. decision) (“An offer
    cannot be accepted unless the offeree actually knows of the offer’s existence.”
    (emphasis added)), with Hagin v. Fireman’s Fund Ins. Co., 
    88 Ariz. 158
    , 162
    (1960) (holding that an insurance company effectively modified an implied
    contract term permitting late payments by mailing notice to its customer
    because “where all that [the insured] had to do was to open their mail, they
    are charged with constructive notice”). Darner provides no insight because
    it obviated the issue by effectively modifying the parol evidence rule. See
    
    140 Ariz. at 391
     (describing its adoption of the Restatement (Second) § 211
    as “basically a modification of the parol evidence rule when dealing with
    contracts containing boiler-plate provisions which are not negotiated, and
    often not even read by the parties”).
    ¶22           This framework also fails to address whether additional
    consumer protections are necessary in this context, such as (1) requiring
    express notice that the business may unilaterally modify terms and that the
    consumer’s failure to opt out constitutes acceptance, cf. SouthTrust Bank,
    
    775 So. 2d at 185
     (observing that initial terms contained an express change-
    in-terms clause); and (2) ensuring the consumer’s ability to opt out of
    proposed modifications without penalty, i.e., to reject a proposed
    8
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    modification and maintain the status quo business relationship. 2 See
    Restatement § 3(a)(2). Consequently, we are tasked with filling this gap in
    the common law.
    II.
    ¶23              In the absence of binding precedent, we follow the
    Restatement if it sets forth sound legal policy. See In re Sky Harbor Hotel
    Props., LLC, 
    246 Ariz. 531
    , 533 ¶ 6 (2019). Notably, we have followed the
    Restatement of Contracts in interpreting and enforcing standardized
    contracts. See Darner, 
    140 Ariz. at 391
    . We also have followed draft
    statements. See, e.g., Sullivan v. Pulte Home Corp., 
    232 Ariz. 344
    , 346 ¶ 10
    (2013) (illustrating the Court aligning its opinion “with the most recent
    draft of the Restatement” (citing Restatement (Third) of Torts: Liability for
    Economic Harm § 3 cmt. a (Am. L. Inst., Tentative Draft No. 1, 2012)));
    Peagler v. Phx. Newspapers, Inc., 
    114 Ariz. 309
    , 315 (1977) (“We hold the
    standard adopted in the Tentative Draft of the . . . Restatement (Second) of
    Torts . . . is the standard to be followed in this State.”).
    A.
    ¶24            Restatement § 3 offers an effective modification procedure
    that fairly balances the public policies of economic efficiency and consumer
    protection:
    (a) A modification proposed by the business of a standard
    contract term in a consumer contract governing an ongoing
    relationship is adopted if the business demonstrates that:
    (1) the consumer received reasonable notice of the
    proposed modified term and a reasonable opportunity to
    review it;
    (2) the consumer received a reasonable opportunity,
    including reasonable notice of the opportunity, to reject
    2 To preserve the at-will nature of the relationship, businesses must be
    allowed to terminate the relationship if the consumer refuses to accept the
    new terms. Accordingly, Restatement § 3 balances consumer and business
    interests by recognizing this termination power subject to certain
    requirements: Businesses must expressly reserve this termination power in
    the agreement’s initial terms, and they may exercise it only if termination
    will not cause “unreasonable cost, loss of value, or personal burden.”
    Restatement § 3(b).
    9
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    the proposed modified term and continue the contractual
    relationship under the existing term, and;
    (3) the consumer received reasonable notice that
    continuing the contractual relationship without rejecting
    the proposed modified term will result in the
    modification being adopted; and
    (4) the consumer either:
    (A) manifested assent to the modified term, or
    (B) did not reject the proposed modified term and
    continued to take the benefit of the contractual
    relationship after the expiration of the rejection period
    provided in the proposal.
    Id. Thus, Restatement § 3’s central rule is that a business’s changes of its
    standard contract terms are binding on its at-will consumers if (1) the
    consumers received reasonable notice of the changes and of an opportunity
    to opt out without penalty; and (2) the consumer continues to do business
    past a reasonable rejection period. Id. There is no actual notice
    requirement. Id.
    B.
    ¶25            Restatement § 3’s position merits our adoption—it is
    consistent with Arizona law and sets forth sound policy. Notably, it aligns
    with our prior decisions recognizing effective modification through silent
    conduct. See, e.g., Hagin, 
    88 Ariz. at 162
     (finding effective modification of
    an implied term allowing late payments where the offeree received
    constructive notice that strict compliance with the agreement’s express
    payment schedule would be thereafter required and the offeree failed to
    object); Restatement (Second) § 19(3) (“The conduct of a party may manifest
    assent even though he does not in fact assent.”).
    ¶26           Restatement § 3’s approach also permits businesses to readily
    update their terms, which facilitates economic efficiency in the context of
    standardized contracts.        Darner, 
    140 Ariz. at 391
     (characterizing
    standardization as “essential ‘to a system of mass production and
    distribution.’” (quoting Restatement (Second) § 211 cmt. a)). Similarly, by
    rejecting an actual notice requirement, Restatement § 3 simplifies business
    operations and reduces transaction costs to the advantage of all parties
    concerned. It makes little sense to require parties to quit their at-will
    relationship just to immediately resume it with additional terms. See
    Johnson, 
    886 N.W.2d at 392
     (“We do not require formalistic language
    10
    CORNELL V. DESERT FINANCIAL CREDIT UNION ET AL.
    Opinion of the Court
    terminating an at-will contract before a change in terms will be effective
    going forward.”).
    ¶27           We also recognize that Restatement § 3’s position imposes
    several safeguards to protect consumers from unfair exploitation. For
    example, businesses must propose modifications in good faith, and new
    terms cannot undermine negotiated parts of the original bargain.
    Restatement § 3(c); see also Rawlings v. Apodaca, 
    151 Ariz. 149
    , 153 (1986)
    (“The law implies a covenant of good faith and fair dealing in every
    contract.”); Wagenseller v. Scottsdale Mem’l Hosp., 
    147 Ariz. 370
    , 383 (1985).
    ¶28            Consumers also must receive reasonable notice that their
    failure to opt out of proposed modifications constitutes acceptance, and
    they must be given a reasonable opportunity to opt out without penalty.
    Restatement § 3(a); see also Duling v. Mid Am. Credit Union, 
    521 P.3d 1145
    ,
    1154 (Kan. Ct. App. 2022) (“[F]ailure to opt-out of a voluntary arbitration
    program constitutes acceptance, especially where [it] is the exact form of
    acceptance [expressly] invited by the offer.” (quoting Rittenhouse v.
    GlaxoSmithKline, No. 21-1836, 
    2021 WL 6197361
    , at *4 (E.D. Pa. Dec. 30,
    2021))). At minimum, “reasonable notice” requires that the initial terms or
    the notice of the proposed modification expressly indicate the consumer’s
    ability to opt out and that failure to do so manifests the consumer’s binding
    assent. Restatement § 3(a); see also Miracle-Pond v. Shutterfly, Inc., 19 CV
    04722, 
    2020 WL 2513099
    , at *6 (N.D. Ill. May 15, 2020) (finding effective
    modification where the business gave notice of new terms pursuant to an
    express change-in-terms clause in the initial terms).
    ¶29          These consumer safeguards supplement—and do not
    supplant—other contract defenses. See A.R.S. § 47-2302 (unconscionability);
    Darner, 
    140 Ariz. at
    391–92 (reasonable expectations). In other words, the
    requirements for effective modification under Restatement § 3 do not
    preclude the application of other contract law.
    CONCLUSION
    ¶30             We answer the first certified question in the affirmative. In an
    on-going, at-will, business-consumer relationship, effective modification of
    the relationship’s governing terms occurs if the business demonstrably
    satisfies the requirements of Restatement § 3 (as set forth in the Opinion and
    as follows): Consumers must (1) receive express and reasonable notice of
    the business’s right to unilaterally modify the agreement; (2) receive
    reasonable notice of new terms and the opportunity to opt out without
    11

    Opinion of the Court
    penalty; and (3) upon receiving actual or constructive notice of new terms,
    continue the business relationship past a reasonable opt-out period. Our
    holding does not foreclose the applicability of contract defenses. We
    decline to answer the second certified question as moot.
