Posting this thread as a heads up for other forum users. Purchased a GTX580 from this user, last communication was on 1/26 when he informed me the card had not gone out but would go out the next day (payment date 1/22). After receiving a Windows COA from him in a timely and professional manner, I did not have any qualms about sending the $60 through Google Wallet to him. Have been giving him the benefit of the doubt, but with no communication in over 2 weeks despite him having been on as recently as an hour ago, I think I'm out of luck on this one.
