I actually found the code earlier, but left it for someone else since I had already own and beat BG&E on another console and didn't have any interest in replaying it.
Surprised it took so long for someone to redeem it, or that someone could notice one code but not the other (since the glitch was the website displaying the header again inside the message box, it would be common sense to look in the same place both outside and inside pages). Also, that the inner code was found first.
Or maybe people found both but thought the outer code had been taken first because it was easier to find, like I did.
