My bidding "stratage" (done mostly because I'm usually not at the computer at the end of the auction):
If not bid on yet, bid early with a max I'd feel good with if I won, but low enough that I have space later. If over bid, see below.
If prior bid is still low, still bid early, but with a lower max than if there was no prior bid. If over bid, see below.
If bid is nearing my "low end max" or I was over bid, I try to remember to snipe. (Then usually unintentionally forget or be too busy at auction end
) In the rare case I am online, I prep two snipes: a low-to-mid "good" price, and a "near the top" max price. I snipe the lower bid with ~ 1 minute left. If I'm outbid or over sniped, I still have the second one and time to use it, if I really want to. After I deside my "near the top" price is really too high for me, I refresh and find that 3 people sniped at higher bids than I would have gone anyway.
I only have won with my "first person to bid" and my "low-to-mid snipe" bids. *shrug*
A real auction also doesn't last for several days--there is a time limit, albeit an arbitrary one (the auctioneer decides when it's been too long between bids, going once, going twice...)
Some "real" auctions take several days, although they're usually "blind" auctions. House sales are one example, with no set end time.
My parents have gotten their last few cars through the California Highway Patrol used patrol car auctions; there's a minimum bid price for each car, the bids are placed sealed in a box, and once a week the bids are examined. The highest bid (if any) for each car wins. Usually a car lasts a few weeks before someone bids on it, more than two bids on a car at once is high.
I'm not sure if
you would call them "real auctions", though.
I have wished auctions on ebay were shorter, but then it would easier for me to miss an object, and harder for the seller to get a (more profitable) bid war. There are (were?) short auction sites, but all the stuff there was at retail prices since the sellers knew there was only enough time for only one or maybe two people interested in the thing to find it and "bid". (That is, when I last looked.) I can see the minimum price racking
way up if ebay started doing 4 hour auctions, and more importantly, me never finding a live auction of stuff I want. *shrug* Not sure if it would really be any better.
