S.C. Code Ann. § 38-78-55: Automatic renewal provisions unenforceable unless certain conditions are met.

No automatic renewal provision in a service contract shall be enforceable against the contract holder unless the contract holder was presented written or electronic notification of that automatic renewal provision not less than thirty days nor more than sixty days before the cancellation deadline required by the automatic renewal provision. This notification shall conspicuously disclose:

(A) that unless the service contract holder cancels the contract, the contract will automatically renew;

(B) the amount that will be charged upon renewal; and

(C) methods by which the service contract holder may obtain details of the automatic renewal provision and cancellation procedure, which shall include a toll-free telephone number, electronic email address, a postal address if the seller directly bills the consumer, or another cost-effective, timely, and easy-to-use mechanism for cancellation.
