And another thing with auction sites is the Shrill bidders
people who bid high on their friends auctions then pull out just at the last 10min before auctions finishes - they stick out like sore thumbs, they bid one after the other then all a sudden stop when it gets to a certain price, to be certain its not just a bidder being honest i usually check out there bidding and find they never finish a bid and its always on the same auctions not theres.
