Totally forgot that I grabbed codes for the Sonic and Tails Avatar hoodies from PAX East. Enjoy.
Sonic, Female: 7HPKY-DV2Q7-YMR3W-Q7FKJ-64MKZ
Tails, Male: H3VCY-WJC63-FRGW7-6RJRF-WH4TZ
Tails, Female: YK43V-VGXVK-M4QTK-VMJ7F-W7MYZ
There you go, $9 worth of junk, because I love CAG (even though I've never once managed to get a free code for anything).
