Yup, it's called Proxy Bidding. But that assumes you won't change your mind later.
The problem is that the very act of bidding on something draws attention to it. If nobody bids until the last minute you don't get very many looky-loos bidding on the stuff, or if you do it's only the folks looking for a super-cheap deal. Which is why there's a market for sniping services I guess.
It's sort of like poker; you don't give away your hand until the last possible minute in order to stay on top.
Exactly. In the offline world, there are all sorts of auctions. I remember before eBay there were "sealed bid" auctions for collectibles ran on newsgroups. In a sealed bid auction, the "auctioneer" (some guy who wanted to get the most he could for stuff he had) would give a list of stuff he wants to auction, with minimum bid prices, and would tell other people on the newsgroup who were interested in the stuff to make their bid "i.e., their best offer) by a certain (usually the deadline was a couple weeks to a month after the initial anouncement of the auction). In this way, no one knew who was willing to pay what for a given item, and it was a pretty good way for the person selling to come to an agreement on the "worth" or "value" of a given item with another party.
In another type of newsgroup auction, people would email in their bids day after day, and the "auctioneer" would have a lot more work to do, updating and sending out "current minimum bids" for each item.
eBay improved upon this by automating the system for the seller, and using http (html (webpages) viewable with a web-browser - a tool "the common folk" can use) instead of nntp (text only newsgroups, viewable with text only news-readers - a tool used exclusively by geeks, at least in 96). However, depending on which type of bidder you are, you can bid daily, checking back on the auction to see if you are ahead, or can set up a program to "reveal how much you are willing to pay" at the end of the auction (like a sealed bid auction). Don't get mad at eBay about it, just bid what you are willing to pay, before the auction ends, and if you are the person who bid the most before the auction ended, you will win. The benefit of sealed bidding is that you don't drive up the price any more than necessary by having "bidding wars", and the benefit of bidding from the time you see the auction til it ends is that you can scare potential bidders away.
Someone said that sniping is a way to avoid shill bidding, but that's not really true. A seller might not be able to bump you up to the most you are willing to pay, but a seller is still able to bump the price up to the least amount he is willing to sell for, by using a shill.
