I only got one receipt, though. They charged me 3 times for the game, and I got the 79.99 version. Those of you who bought it over the weekend, check your statements. I think it was because the servers were all messed up, but I'm going to call and find out.
EDIT: Oh, and don't think I'm criticizing the game - I really like it. It's different from your typical MMO. I just wanted to offer a heads up in case anyone else had this issue.
