Halo 4 Double XP codes

Hey UG'ers Are you drinking a Mountain Dew of eating a bag of Doritos? Does it have a special code for double XP for Halo 4? I don't drink much dew or eat many doritos but I am in need of some double xp codes. So if you have any of these codes and don't play Halo I would greatly appriciate your codes! Send them to me via message and I will be your best friend!

Thanks

Dude bro go to Walmart, shoppers, 711 safeway, etc. and just copy them Phone Post

I have friends who have done that, but I don't want to be THAT Asshole. I imagine some kid saving all of his allowance to buy a cold pop, then he tries to use the code and its invalid cause some jackass stole it.

Anyone????
