for a "regular" auction...only the current high bid amount and prior lower bids (if any). I don't bid on many "reserve" auctions...I just don't like trying to "chase" the reserve amount. If it's something that really want, I'll e-mail the seller to ask what the reserve amount is...sometimes a get a nice response, sometimes none, sometimes I get "Bid it up until you find out" (I won't ).

I agree that the best way to set your "reserve" amount is to actually start the auction at the lowest amount that you'll accept for the item. Steve B
