La. Stat. tit. 9 § 3536
With respect to a consumer credit transaction, the extender of credit may not give or offer to give a rebate or discount or otherwise pay or offer to pay value to the consumer as an inducement for a sale in consideration of his giving to the extender of credit the names of prospective purchasers or otherwise aiding the extender of credit in making a sale to another person, if the earning of the rebate, discount or other value is contingent upon the occurrence of an event subsequent to the time the consumer agrees to buy. If a consumer is induced by a violation of this Section to enter into a consumer credit transaction, the agreement is unenforceable by the extender of credit and the consumer, at his option, may rescind the agreement or retain the goods delivered and the benefit of any services performed, without any obligation to pay for them.
