We support Extended Bidding. If a bid is received within the last 4 minutes of an item's auction, we will extend that item another 4 minutes. This gives anyone who is outbid a fair chance to win the item back.
You can find this policy in our auction Terms & Conditions, at the top of every auction page, and on each item page. To offer further clarification, there is a difference between the "Auction End" time and the time an individual item ends. We stagger the ending of all our items, we say our auction "begins closing" at 7 pm.
For example, the first item in our auction ends at 7 pm, the next one ends at 7 pm and 30 seconds and the next one ends at 7:01. When we have 500+ items, the last item may not end until after 10 pm.
