S.C. Code Ann. § 59-119-1010

The bonds may be disposed of in such manner as the trustees shall determine, except that no privately negotiated sale without public advertisement may be made without the prior approval of the State Fiscal Accountability Authority. If the trustees shall elect to sell the bonds at public sale, at least one advertisement thereof shall appear in a newspaper of general circulation in the State not less than seven days prior to the occasion fixed for the opening of bids. The bonds may be sold at such discount or for such premium as may be determined by the trustees or their designee as being in the best interest of Clemson.
