Idaho Code § 28-43-308
With respect to a regulated consumer credit sale, the seller may not give or offer to give a rebate or discount or otherwise pay or offer to pay value to the debtor as an inducement for a sale for the debtor giving to the seller the names of prospective buyers, or otherwise aiding the seller 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 after the time the debtor agrees to buy. If a debtor is induced by a violation of this section to enter into a regulated consumer credit sale, the agreement is unenforceable by the seller and the debtor, at his option, may rescind the agreement or retain the property delivered and the benefit of any services performed, without any obligation to pay for them.
