Reserve Auctions.

Reserve auctions are for sellers who don’t want their items to sell for less than a certain price – a concept you’ll know about if you’re familiar with real auctions. They work just like normal auctions on eBay, except that you will be told if your bid has not met the reserve price set by the seller. If no-one is willing to meet this price, then the auction is cancelled, and the seller keeps the item.

You can spot these auctions by looking out for ‘Reserve not met’ or ‘Reserve met’ written next to the current bid on an item’s description page.
