No, there is no charge. Please bear in mind that you must pay for the item you won, however, right away, if you plan on bidding on more items. This seems like a neat feature, but it conflicts with the ability pre-bid on certain items. If you pre-bid on few items, your bid will be recognized only on 1st item. If no payment received upon the end of the auction, your other pre-bids will be annulled, so please keep that in mind.
