Halo 4 Specializations

Hey guys, I've been hopelessly exploiting my doritos double xp in halo, but as I played on the 21st (urgh!) I did not receive the code to unlock all specializations. I was wondering if any of you who got the limited edition and have two codes, or have no need for the code would mind giving me theirs. I would greatly appreciate it, and am willing to do something in return, whether that be through double xp, or some other form of payment... Unless you want do do it out of holiday spirit . Oh yeah, happy holidays!
