S.C. Code Ann. § 61-4-40: Credit sales prohibited.

A holder of a beer permit or a beer and wine permit may not purchase beer or wine, or both, on credit by a dishonored check, an unpaid note or invoice, or other insufficient manner from a permitted beer and wine wholesaler. However, no action may be taken against the holder for a first violation of this section. If a holder commits a second or subsequent violation, his retailer's permit may be suspended, canceled, or revoked by the department, or a monetary penalty of not more than twenty-five dollars may be assessed against him.
