haha you guys are funny
I used to do the same thing a few years back....
Id say (after auction ends) that I would like to fly out and pick up the card in person, meet him at his bank or the police station, or where ever he wanted where I would pay for the card with a Cashiers Check... Love to watch them squirm and make up all kinds of excuses where they have to do the transaction only through the mail, etc.
Sometimes Id even look up thier location and find some small town next to theirs, and say Im going to visit my parents in a few day in so and so town and would like to do the transaction in person , etc. fun stuff.
Ive been suspended a couple times too by eBay for auction interference, so have cut back a bit on messing w/scammers.
