(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.
