S.C. Code Ann. § 61-6-1500
No retail dealer may:
(6) redeem proof-of-purchase certificates for any promotional item.
However, during restricted hours retail dealers are permitted to receive, stock, and inventory merchandise, provide for maintenance and repairs, and other necessary, related functions that do not involve the sale of alcoholic liquors.
The provisions of this section relating to quantities of less than two hundred milliliters do not apply to (1) minibottles when authorized by law to be sold to persons licensed to sell minibottles for on-premises consumption or (2) minibottles sold for consumption on commercial aircraft engaged in interstate commerce.
It is unlawful for a person licensed to sell alcoholic liquors under the provisions of this section to refill a minibottle. A person who violates this provision must, upon conviction, have his license revoked permanently.
A retail dealer must keep a record of all sales of alcoholic liquors sold in minibottles. The record must include the name of the purchaser and the date and quantity of the sale.
It is unlawful to sell minibottles except during lawful hours of operation.
A retail dealer who sells alcoholic liquors in minibottles to a person not licensed under Article 5 of this chapter is guilty of a misdemeanor and, upon conviction, must be fined not more than one thousand dollars and his retail dealer's license may be suspended or revoked in the discretion of the department. As used in this paragraph, "a person licensed under Article 5 of this chapter" includes his designated agent as a purchaser.
