(b) The governmental body shall offer such supply through competitive sealed bids, public auction, or established markets.

(c) Notice of sale by bid or auction shall conform with the procedures set forth in paragraph (c) of section five. The notice shall indicate the supply offered for sale, designate the location and method for inspection of such supply, state the terms and conditions of sale including the place, date and time for the bid opening or auction, and state that the governmental body retains the right to reject any and all bids.

(d) If the governmental body rejects the bid of the highest responsive bidder, the governmental body may:

(1) negotiate a sale of such supply so long as the negotiated sale price is higher than the bid price; or

(2) resolicit bids.

(e) A procurement officer may trade-in a supply listed for trade-in in the invitation for bids or request for proposals.
