Where can I get DLC codes for free?

(I know, I know I'm /that/ person, but seriously I'm a broke <censored> college student)

just as the title says, if any one has an extra code or something, or you know where to generate one, that would rock. I only have the 3ds one and I don't see myself even affording a Wii U anytime in the next few years p:

The closest you'll get to "free" is someone offering their code in the Nookling Junction for Play Coins or in a giveaway. It is impossible to "generate" a code and have it work, sorry =/
