S.C. Code Ann. § 39-9-180: Declaration of quantity required in advertisement stating retail price.

Whenever a packaged commodity is advertised with the retail price stated, there must be associated closely and conspicuously with the retail price a declaration of quantity as required by law or regulation to appear on the package. Where a dual declaration is required, only the declaration that sets forth the quantity in terms of the smaller unit of weight or measure must appear in the advertisement.
