Because games come out on Tuesday I say put it in the mail on the 7th. That should give you enough time for them to get your game. Also have ONLY the UFC game that you want in your Q so thats all they will send.
Did they get the game? Have they shipped out Man v Wild? If they shipped it then wait 5 or 7 days and if it still hasn't come there may be a shipping problem. In which case you should report it to them and they should send another copy.
