Cal. Bus. & Prof. Code § 17537.1

(a) It is unlawful for any person, or an employee, agent, or independent contractor employed or authorized by that person, by any means, as part of an advertising plan or program, to offer any incentive as an inducement to the recipient to visit a location, attend a sales presentation, or contact a sales agent in person, by telephone, or by mail, unless the offer clearly and conspicuously discloses in writing, in readily understandable language, all of the information required in paragraphs (1) and (2). If the offer is not initially made in writing, the required disclosures shall be received by the recipient in writing prior to any scheduled visit to a location, sales presentation, or contact with a sales agent. For purposes of this section, the term “incentive” means any item or service of value, including, but not limited to, any prize, gift, money, or other tangible property.
1. (1) The following disclosures shall appear on the front (or first) page of the offer:
  1. (A) The name and street address of the owner of the real or personal property or the provider of the services which are the subject of the visit, sales presentation, or contact with a sales agent. If the offer is made by an agent or independent contractor employed or authorized by the owner or provider, or is made under a name other than the true name of the owner or provider, the name of the owner or provider shall be more prominently and conspicuously displayed than the name of the agent, independent contractor, or other name.
  2. (B) A general description of the business of the owner or provider identified pursuant to subparagraph (A), and the purpose of any requested visit, sales presentation, or contact with a sales agent, which shall include a general description of the real or personal property or services which are the subject of the sales presentation and a clear statement, if applicable, that there will be a sales presentation and the approximate duration of the visit and sales presentation.
  3. (C) If the recipient is not assured of receiving any particular incentive, a statement of the odds of receiving each incentive offered or, in the alternative, a clear statement describing the location in the offer where the odds can be found. The odds shall be stated in whole Arabic numbers in a format such as: “1 chance in 100,000” or “1:100,000.” The odds and, where applicable, the alternative statement describing their location, shall be printed in a type size that is at least equal to that used for the standard text on the front (or first) page of the offer.
  4. (D) A clear statement, if applicable, that the offer is subject to specific restrictions, qualifications, and conditions and a statement describing the location in the offer where the restrictions, qualifications, and conditions may be found. Both statements shall be printed in a type size that is at least equal to that used for the standard text on the front (or first) page of the offer.
2. (2) The following disclosures shall appear in the offer, but need not appear on the front (or first) page of the offer:
  1. (A) Unless the odds are disclosed on the front (or first) page of the offer, a statement of the odds of receiving each incentive offered, printed in the size and format set forth in subparagraph (C) of paragraph (1).
  2. (B) All restrictions, qualifications, and other conditions which must be satisfied before the recipient is entitled to receive the incentive, including, but not limited to:
    1. (i) Any deadline by which the recipient must visit the location, attend the sales presentation, or contact the sales agent in order to receive an incentive.
    2. (ii) Any other conditions, such as a minimum age qualification, a financial qualification, or a requirement that if the recipient is married or in a registered domestic partnership, both spouses must be present in order to receive the incentive. Any financial qualifications shall be stated with a specificity sufficient to enable the recipient to reasonably determine his or her eligibility.
  3. (C) A statement that the owner or provider identified pursuant to subparagraph (A) of paragraph (1) reserves the right to provide a raincheck, or a substitute or like incentive, if those rights are reserved.
  4. (D) A statement that a recipient who receives an offered incentive may request and will receive evidence showing that the incentive provided matches the incentive randomly or otherwise selected for distribution to that recipient.
  5. (E) All other rules, terms, and conditions of the offer, plan, or program.
(b) It is unlawful for any person making an offer subject to subdivision (a), or any employee, agent, or independent contractor employed or authorized by that person, to offer any incentive when the person knows or has reason to know that the offered item will not be available in a sufficient quantity based upon the reasonably anticipated response to the offer.
(c) It is unlawful for any person making an offer subject to subdivision (a), or any employee, agent, or independent contractor employed or authorized by that person, to fail to provide any offered incentive which any recipient who has responded to the offer in the manner specified therein, who has performed the requirements disclosed therein, and who has met the qualifications described therein, is entitled to receive, unless the offered incentive is not reasonably available and the offer discloses the reservation of a right to provide a raincheck, or a like or substitute incentive, if the offered incentive is unavailable.
(d) If the person making an offer subject to subdivision (a) is unable to provide an offered incentive because of limitations of supply, quantity, or quality that were not reasonably foreseeable or controllable by the person making the offer, the person making the offer shall inform the recipient of the recipient’s right to receive a raincheck for the incentive offered, unless the person making the offer knows or has reasonable basis for knowing that the incentive will not be reasonably available and shall inform the recipient of the recipient’s right to at least one of the following additional options:
1. (1) The person making the offer will provide a like incentive of equivalent or greater retail value or a raincheck therefor.
2. (2) The person making the offer will provide a substitute incentive of equivalent or greater retail value.
3. (3) The person making the offer will provide a raincheck for the like or substitute incentive.
(e) If a raincheck is provided, the person making an offer subject to subdivision (a) shall, within a reasonable time, and in no event later than 80 days, deliver the agreed incentive to the recipient’s address without additional cost or obligation to the recipient, unless the incentive for which the raincheck is provided remains unavailable because of limitations of supply, quantity, or quality not reasonably foreseeable or controllable by the person making the offer. In that case, the person making the offer shall, not later than 30 days after the expiration of the 80 days, deliver a like incentive of equal or greater retail value or, if an incentive is not reasonably available to the person making the offer, a substitute incentive of equal or greater retail value.
(f) Upon the request of a recipient who has received or claims a right to receive any offered incentive, the person making an offer subject to subdivision (a) shall furnish to the person sufficient evidence showing that the incentive provided matches the incentive randomly or otherwise selected for distribution to that recipient.
(g) It is unlawful for any person making an offer subject to subdivision (a), or any employee, agent, or independent contractor employed or authorized by that person, to:
1. (1) Use any printing styles, graphics, layouts, text, colors, or formats on envelopes or on the offer that imply, create an appearance, or would lead a reasonable person to believe, that the offer originates from or is issued by or on behalf of a government or public agency, public utility, public organization, insurance company, credit reporting agency, bill collecting company, or law firm, unless the same is true.
2. (2) Misrepresent the size, quantity, identity, value, or qualities of any incentive.
3. (3) Misrepresent in any manner the odds of receiving any particular incentive.
4. (4) Represent directly or by implication that the number of participants has been significantly limited or that any person has been selected to receive a particular incentive unless that is the fact.
5. (5) Label any offer a notice of termination or notice of cancellation.
6. (6) Misrepresent, in any manner, the offer, plan, or program or the affiliation, connection, association, or contractual relationship between the person making the offer and the owner or provider, if they are not the same.
(h) If the major incentives are awarded or given at random, by the assignment of a number to the incentives, that number shall be actually assigned by the party contractually responsible for doing so. The person making an offer subject to subdivision (a) hereof, or the agent, employee, or independent contractor employed or authorized by that person, if any, shall maintain, for a period of one year after the date the offer is made, the records that show that the winning numbers or opportunity to receive the major incentives have been deposited in the mail or otherwise made available to recipients in accordance with the odds statement provided pursuant to subparagraph (C) of paragraph (1) of subdivision (a) hereof. The records shall be made available to the Attorney General within 30 days after written request therefor. Postal receipt records, affidavits of mailing, or a list of winners or recipients of the major incentives shall be deemed to satisfy the requirements of this section.
