Depending on the type of auction you are bidding on, some may be moving more quickly than others. If you placed a bid and are no longer the highest bidder, chances are it is because someone else has placed a bid a fraction of a second after yours and, therefore, has become the new highest bidder. One way to verify is to look at the Bidding History on the right hand side of the Details Page. There you will find the last ten bids placed in that auction as well as the names of the members placing them. Should this not be the case and you are simply experiencing technical difficulties, please contact our Support Team and they'll be more than happy to help.
