I submitted a bid amount for a refurbished item, which is like new. Is that acceptable?

No. The Request for Bids Instructions state that "your bid price must be rational, feasible, supportable, and reflect all costs associated with providing the lead item and services" and that you should "carefully review your bid amounts for keying errors and to ensure you are correctly entering either a purchase or rental amount for a new item as instructed." Bidders were required to submit a bid amount for a new item, as opposed to refurbished, like new, or used, to help ensure the integrity of the bidding process.
