No seller in a home solicitation sale shall offer to pay a commission or give a rebate or discount to the buyer in consideration of the buyer's giving to the seller the names of prospective purchasers or otherwise aiding the seller in making a sale to another person, if the earning of the commission, rebate or discount is contingent upon an event subsequent to the time the buyer agrees to buy.
