S.C. Code Ann. § 11-43-620

Transportation infrastructure bonds must 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 must be awarded to the bidder offering to purchase the transportation infrastructure 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 is reserved to reject all bids and to readvertise the bonds for sale and to waive technicalities in the bidding.
