This means that you are bidding in a Reserve Price Auction. A reserve price is the lowest price a
seller is willing to sell the item for. It should be higher than the minimum bid price and is usually
kept secret from buyers. If your maximum bid is lower than the seller's reserve, "reserve not yet met"
will remain next to the item price. On the other hand, let's say the minimum bid amount is £15 and the
seller's reserve is £50. If you place a maximum bid of £75, your bid will jump to £50 and the words
"reserve met" will replace "reserve not yet met."
Sellers use reserve prices to stimulate interest in their items. By starting the bidding
lower and adding a reserve price, the item will generally receive more bids. Please note that if
you bid on a Reserve Price Auction and your bid does not meet the reserve, you have no
obligation to purchase the item from the seller.
