DubLi lowest prices worldwide with unique Bid auctions. how it works? All auctions are presented for a limited time only. You can bid using any number of 20 cent increments (e.g. 1 euro, 2.20 euro, 3.80 euro etc.). The user who has placed the sole lowest bid is the winner. An example: several people have placed bids worth 1 euro, 2 euro, 3.20 euro, 4.40 euro and 5.00 euro. The amounts 3.20 and 4.40 euro were both placed once, whereas 3.20 euro is both the lowest singular bid, and therefore is the winner. If another user places a bid of 3.20 euro in the course of the auction, this amount is no longer unique. Now, in our example, the 4.40 bidder would be the winner, as their bid is now the lowest single bid placed. It is possible to place single bids, or to cover an entire span of bids. However, in order to guarantee equal opportunity, only single bids will be accepted in the last five minutes before the end of an auction.
