Popcorn bidding is a feature that was implemented at the request of GoMotorBids Members. It is a feature that automatically extends the closing time of an item listing if a bid is placed within the last few minutes of the auction. If yet another bid is placed, the time will be extended again. Bids may be placed until all bidding activity ceases. This enhancement makes the listing more like a traditional "live" auction in that as long as there is interest and activity on an item, bidding will continue. It also prevents a practice known as "sniping", where bidders place a bid to take an item away from another bidder in the last seconds before the listing closes.

Popcorn bidding is only in effect for the 24 hour auction and auctions for charitiable foundations. You will see a special icon in the item listing for popcorn bidding.
