Isn't then the Johnny come lately just sniping the sniper's bid? (not that I have a problem with it, it just doesn't seem to fix the problem of people bidding at the last minute)
Actually there are plenty of sealed bidding situations in the world. That is the model adopted by ebay. We have already heard of many examples where things already go for more than retail. Ebay to continue has to be beneficial to both buyers and sellers. If buyers are turned off by high prices they won't bother anymore and ebay will die. Remember that the buyer is the one person in the whole ebay world who is willing to pay the price for the item. What good would squeezing a few more dollars out of him do? The popularity of ebay by both buyers and sellers seems to suggest (not prove) that they are doing a decent job of balancing the needs of both.
