A seller may not use multiple agreements with respect to a single consumer credit sale with intent to obtain a higher rate of credit service charge than would otherwise be permitted by the provisions on credit service charges for consumer credit sales (Section 37-2-201). The excess amount of credit service charge resulting from a violation of this section is an excess charge for the purpose of the provisions on rights of parties (Section 37-5-202) and the provision on civil actions by the Administrator (Section 37-6-113).
