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 5 minutes of an auction, the auction will automatically extend for an additional 5 minutes from the time of the latest bid. The auction will close once all bidding activity has stopped for a period of 5 minutes.
sorry
...the current bid has exceeded the buy now price for this item, so buy now is no longer available.
