Hey, so I pre-ordered Halo 3 online for only $40 and it's going to take a few extra days to arrive. So I went to wal-mart at midnight and picked up the $60 version to play it and then when the preordered copy finally arrives return that one to wal-mart as if it was the one I bought there at midnight. SO I need to know if the UPCs are any different depending on where you got it. So what is your guys' UPC #'s for the normal $60 version. A quick response would be awesome so I could open and play with no worries of being stuck with two copies.
