Watch out
If auction is not from UBid directly (Consumer Exchange, I think), proceed with EXTREME caution. There are tons of auctions from people claiming to be in Europe and wanting you to use money wiring. NEVER EVER EVER EVER wire money out of the country. You'll never see it again. Ubid even includes this warning in their winning bid email. They say, "if it's too good to be true, it probably isn't"
The whole final call thing is that no one has to bid for 10 straight minutes after the auction ends, in order to really end. Everytime someone bids, the 10 minutes gets extended.
Also, their shipping fees are pretty high.
Basically, don't get blinded by a seemingly good deal....and use common sense.
