If you have an auction-style listing with Best Offer, bear in mind that:

If you receive a bid
Current offers and counteroffers will be declined automatically, and buyers won't be able to make any additional offers on your item
If you had received an offer that was higher than the current bid, the buyer who made the offer will need to place a bid, as their offer was declined when the first bid was placed
If a bidder retracts their bid, the Best Offer feature will be re-enabled
