I've done that chilly. Get in early and bump it to your max. Keeps a lotta flies off figuring you really want it. Once they bid and bid and bid and you keep on top they don't know where the end is and sometimes drop out early. Another option is to try to snipe at the very end with like 5 seconds left. This only works on eBay as other actual auction sites have a "+10 minutes" on the auction at every new winning bid. Auctions do provoke bidding wars and often people pay more, sometime waaaay more than the item is actually worth.
