I like Gunbroker's 15 minute rule.
Anyone really know why eBay doesn't run like a true auction?
Ebay is a true auction. There are many different types of auctions, and it's just not a traditional "Going, Going, Gone" type auction(AKA an English Auction). Sites that extend bidding due to last second bids operate this way.
Ebay could best be classed as a sealed-bid Vickrey type auction, where the bids are sealed(i.e. the amount not known) and the price the winning bidder pays is determined by the second highest bidder. Ebay is a bit different from a Vickrey type auction in that the winning bidder pays
one bid increment over the second highest bid(except in special cases where the two highest bidders are separated by an amount less than a bid increment).
I've been around Ebay-first using my Dad's account and later my own-since 1998.
Sniping is how it works on Ebay. It always has, and is most likely not going to change. There's nothing "unfair" about it-if you bid the maximum amount you are willing to pay, don't complain about how you "changed your mind."(BTW, even if you enter an early maximum bid, you can still continue to increase it up to the last second of the auction).
I don't have a lot of sympathy for folks who complain about sniping-that's how it's been done on Ebay for nearly 20 years now. Either learn to play the game, or stay away.
There's nothing evil or cowardly about it-it's just people making the most efficient use of the system that's in place.
