[quote name='TripleQ']FF13 console bundle has a different code (same number but with a M at the end). I haven't tried to register it yet though so I'm not sure if it counts as a unique code.[/QUOTE]
you can test the code without using it.. If you enter the code and it says the name of the game with the 50 points, then its good, just hit the back button or close the website. Code will still be unused, and if its been used, it'll say it has already been used, and if you already registered the game and its still unused, it'll say you cannot redeem another game of the same title (or something like that). Hell if you don't need the code and it works, I'd be willing to give you amazon credit once I have it built up, but even if you'd want that, it'd have to be months from now, already ultimate, so no use for it as of right now. But of course, thats only if it is a code that is seperate from the normal ffxiii
