S.C. Code § 57-11-360
State highway bonds shall be sold by the Governor and the State Treasurer upon sealed proposals, after publication of notice of such sale one or more times at least seven days before such sale, in a newspaper of general circulation in the State and also in a financial paper published in New York City which regularly publishes notices of sale of state or municipal bonds. The bonds shall be awarded to the bidder offering to purchase the state highways bonds at the lowest net interest cost to the State at a price of not less than ninety-nine percent of par and accrued interest to the date of delivery, but the right shall be reserved to reject all bids and to readvertise the bonds for sale and to waive technicalities in the bidding.
For the purpose of bringing about successful sales of such bonds, the State Fiscal Accountability Authority may do all things ordinarily and customarily done in connection with the sale of state or municipal bonds. All expenses incident to the sales of such bonds shall be paid from the proceeds of the sale of such bonds.
