Proposals may be modified or withdrawn prior to the established due date in accordance with 1.4.1.20 NMAC of this rule. The established due date is either the time and date announced for receipt of proposals or receipt of modifications to proposals, if any; or, if discussions have begun, it is the time and date by which best and final offers must be submitted by short-listed offerors. (NOTE: if the time a proposal is due is listed as "3 p.m." this means 3:00:00 and not 3:00:59.)
