It has been recently discovered that if you now buy copies of Pokémon X & Y at a Walmart in the states, they will contain special serial codes. If you buy Pokemon X you’ll get a serial code to download a special Garchomp; if you get Y you’ll get one for a special Scizor. Both of these serial codes are one-time use only.
The details of these event Pokemon as well as how long this promotion lasts hasn’t been announced yet, but we’ll be sure to keep you guys updated!
P.S. Happy Thanksgiving, guys!
