He had apparently thought I had only outbid him by one cent, as he bid in at $15 in the final seconds. Good old Auctionsniper. It bids just what it takes to win, and not a cent more.
Actually, that's not quite true. Auctionsniper (which is what I also use, but there are other companies that do it as well) bids
your highest bid...but it's ebay which ultimately decides what bid is needed, and doesn't exceed what is necessary.
So if somebody bid $15, and you bid $100,000 on the same item (I'm making an extreme example), you'll win it for $15.50, I think - I believe the ebay "bid increment" at that level is fifty cents. That attracted me to ebay immediately, because it is so in contrast to closed-bid auctions I've been accustomed to.
In bidding for recordings and such, which appear on a private list, if I want something badly (and the minimum bid if $10) and I bid $73.11 on it, I will invariably be charged $73.11 for it, even if nobody else bid on it. On ebay, I would be charged $10 if nobody else bid, and only $10.50 (?) if one other person bid the bare minimum of $10. In more than 35 years of bidding on stuff, no seller outside of ebay has *EVER* reduced any bid I've ever made on anything. Therefore, anything I want there, I bid my ABSOLUTE maximum in all cases and, on rare occasions, I'll end up paying near my maximum, but usually I'll end up owing far less.
Ebay is actually a "hybrid closed auction" because all bidding is shown, but the bid that you can see can
more accurately be described as "
the bid on this item is AT LEAST this amount, but it may actually be much higher than the amount shown." So, the amount of the true MAXIMUM bid is closed...and during the last 30 seconds, with bid sniping sites being commonly used, an item can change far too quickly for anybody to challenge it and end up winning. If somebody wins something by bidding way out of whack, the actual "very high bid" is never shown - only that the person beat the second bid by whatever bid increment is in effect at that price stratum.
I know a lot of people don't fully understand it, because I've heard friends complain that "Dammit, I really wanted that thing on ebay, and somebody outbid me by one measly dollar at the last minute!" More than likely, both of these things are true: that the other bidder was sniping rather than bidding manually, and that the bid that was put in was actually considerably more than $1 above his/her losing bid.
