The following, when used as part of an advertising plan or program defined in Section 17537.1, are deceptive and constitute unfair trade practices:
Notwithstanding the preceding paragraph, when the offered incentive is a certificate or coupon redeemable for transportation, accommodations, recreation, vacation, entertainment, or like services, the offer may place a condition on the use of the incentive which requires the recipient to pay directly to the transportation company, the accommodation, recreation, vacation or entertainment facility, or similar direct provider of like services, a refundable deposit, not to exceed fifty dollars ($50), to reserve space availability or admission, only if the deposit shall be returned in United States dollars immediately upon the recipient's arrival at the location of the provider to whom the recipient paid the deposit. If the incentive is such a certificate or coupon, and if government-imposed taxes directly related to the service being provided are not included in the incentive, the offer itself, in close proximity to the description of the incentive which is evidenced by the certificate or coupon, shall disclose those government-imposed taxes which will be the recipient's responsibility and the approximate dollar amount of those taxes. A deposit from the recipient may be collected to cover the cost of those government-imposed taxes.
