The Auto Bid Extend feature ensures that bidders will always have a chance to challenge bids placed in the final seconds of an auction. When indicated on a listing page, if a bid is placed during the last 0 minutes of an auction, the auction will automatically extend for an additional 0 minutes from the time of the latest bid. The auction will close once all bidding activity has stopped for a period of 0 minutes.
