S.C. Code § 59-71-530
State school bonds whose proceeds are to be applied exclusively to the purchase of school bus equipment may be privately placed, if the terms and conditions of such disposition shall be approved by resolution duly adopted by the State Fiscal Accountability Authority.
All other State school 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 ten 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 highest bidder at a price not less than 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.
For the purpose of bringing about successful sales of such bonds, the Board 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.
