Codes are only one use aren't they? Cuz my sister had a friend who gave her a pair of spare codes and offered to put it on my 3DS, but of course I don't have my 3DS so I have no use for the code... but I have no way to decide how to give it to someone here (at this point it'd be a tossup for me between owo, Darxmarx, Doq, and Greatest_Aether, assuming single-use...) [my reasoning being Falco buddies/the people I find most kind/hilarious on this board (both really) - and only because I'd otherwise have zero way to narrow it down at all].
If they're not one-use, I'll ask my sister to text me the code and I'll put it up here.
