Sniping is optimal, but go to your max with your last bid. E.g. if you are willing to pay $1,500 for an '09 Scott Addict frame set, don't bid $1,350 with 5 seconds left and lose the auction at $1,375. Also, if the auction starts high, for example $799 for a set of Bontrager XXX tubulars and $799 seems reasonable, but you don't want to go any higher, be the first bidder and just hang-out. Some people might be scared away at the initial high bid and you end up getting the wheel set.
