S.C. Code Ann. § 11-41-140

Bonds must be sold by the Governor and the State Treasurer upon sealed proposals, after publication of notice of the sale one or more times at least seven days before the sale, in a financial paper published in New York City which regularly publishes notices of sale of state or municipal bonds. The bonds may be awarded upon the terms and in the manner as prescribed by the State Treasurer. The right is reserved to reject all bids and to readvertise the bonds for sale. For the purpose of bringing about successful sales of the bonds, the State Treasurer may do all things ordinarily and customarily done in connection with the sale of state or municipal bonds. All expenses incident to the sale of the bonds must be paid from the proceeds of the sale of the bonds.
