Lennyjoe, one website will work for you.
www.esnipe.comI gave up trying to win in a bid auction on e-Bay a long time ago. I switched to sniping in the last 4 seconds of each auction, and I've won darned near every one of them ever since. E-Snipe works great for that.
Of course, you have to have your maximum bid set higher than others who have bid before you with a hidden max amount. Their max, and the e-Bay autobid function, may give you an unpleasant surprise.
And don't put any bids in prior to that last 5 seconds. You're just telegraphing your intentions before then.
It's interesting to sit back and watch something you're auctioning off, or just watching an item to gauge public interest, and see how the manual bidders vs. the bidsnipers run the auction near the end.
The real trick is to try a manual snipe, and win it with as few seconds, and as few dollars, or pennies, as you can. That's where you need an accurate clock, and synchronize your computer with e-Bay's online clock. (I have a Datum 9700 system that locks into a GPS time standard)
My personal best on a manual snipe is 1 second left, and 1 dollar over the non-winning bid. Some have gotten it down to 1 second, and one penny.
