S.C. Code § 29-15-80
If any part of the amount for which goods are held under such lien remains unpaid for a period of sixty days after the earliest item of such amount became due and payable, the lienor may sell such goods at public auction, first (a) publishing a notice of the time and place of such sale once in each of two successive weeks in a newspaper published in the city or town, if any there be, and otherwise in the county, in which the goods are situated, the last publication to be not less than five days prior to the sale, (b) giving five days' notice of such sale by posting in five or more public places in such county, one whereof shall be in the town or city ward in which such goods are situated and (c) if the residence or business address of the owner of the goods is known or can be ascertained, sending by registered mail a copy of such notice to such owner at such address at least five days before the day of sale. But if such goods are readily divisible no more thereof shall be so sold than is necessary to discharge the underlying indebtedness and cover the expenses of the sale. The proceeds of sale shall be applied to the payment of such indebtedness and expenses and the balance, if any, shall be paid to the owner or person entitled thereto. The remedy herein provided to enforce such lien shall be in addition to any other provided by law.
