what sniping does is eliminate the possibility of emotional mindless last minute bidding by someone else on an item that you want.
It even eliminates that possibility in you.
You get the best possible price that can be achieved on this auction.

I have bought bicycles from bare frame through needed components using auctionsniper bidgroups.
One of these two frames is going to work for us.
The Geliano in my daughter's size was nice, but way outbid our interest.
My daughter is very happy with the Fuji, which she built for her summer project. ($154 frame purchase against several bidders, and I didn't attend the auction; also used auctionsniper for Ultegra derailleurs and Chorus brakes)


$171 frame purchase for my Moser using auctionsniper.
It was a "this could work" browsing, searching (24, 25, 62, 63, 64), placed a $190 snipe and went away.
The temporary insanity about this, I actually had instantaneous buyer's remorse when I got the auctionsniper winner e-mail.
I got over it when I received the frame.
Other components bought using auctionsniper bidgroups were crank, FD, Chorus brakes.
