I have one Mew code. The spare one that The Pokemon Company sent out via Email to people who didn't get a chance to get one. I lucked out and was able to get it via Gamestop, so I don't really have any use for the spare. - Code has been traded to another user.
I'm looking for a US $10 PSN code for it (legit ones, please -- I'm familiar with fake ones). PM me with offers if you're interested. Thanks.
If not that, then I'd be more than interested in trading it for any of the following (legit) Eshop game codes:
Super Mario Advance 4: Super Mario Bros. 3
The code is only good through August 31st. So first come, first serve.
Note: This code works with Pokemon X, Y, Omega Ruby and Alpha Sapphire only.
