This is a very strange way of doing buisness. I guess I'm a bit unclear as to whether you actually recieve the card you bid on (or bought)-or do they just find any card matching the description and send it ?
At any rate, communication is always the key to a good deal IMO. And I guess actually owning the card you are selling would make the most sense?
I hope this deal works out for you, and you either get the correct card that you bought, or your money back.
Sincerely, Clayton
