You can submit a bid per the item’s Bid Increment table or place a maximum bid with the amount you are willing to pay for the item. (sellers and other buyers never know the amount of your maximum bid). With a max bid, consign.bid will automatically place bids on your behalf, using the smallest bidding increment necessary to make sure you remain the high bidder or meet the reserve price until bidding reaches your maximum bid.

You do not have to keep coming back to re-bid every time another bid is placed.  If another bidder has placed the same bid before you or a higher maximum bid, we will let you know that you have been outbid so you have the opportunity to place another bid.

However, if no other bidder has a higher maximum bid at the end of the auction, you will win the item even if your current bid is not as high as your maximum bid.  You could end up paying much less than the maximum bid you placed.
