.... and why would this guy need it? I check my credit card and I don't even have a security code on the back of my card.

P.T. Barnum always said... "There's a sucker born everyday" and this guy has already sucked 4 people into his auction.

I don't know about anyone else but I generally don't bid on auctions where the seller has either Zero feedback or any negative feedback, It doesn't matter what the reason for the negative feedback, even if it was put there in error I won't do business with them, I know that may seem harsh but so far I've had a excellent experience with and I have no intention of mucking it up.
