I got two shipping emails for one game, I got one yesterday and one today. I don't know if they charge twice though, because if they were doing that they would have to send two billing sheets. Also in the first email, it only had the game shipping, and in the second one, the game and wrapping was shipping.
Bahamut, can you check your suitemates' order forms and see if the same thing happened to them? I'm a little curious.
But I also figure if they ship two games, one for full price, I can always return one for full credit.
