Xbox 360 Slim Jim Promotion

[GetFresh]

Has anyone bought any slim jims for the Battlefield 4 promotion? Each selected slim jim you buy has a credit value. You can redeem them for bonus XP, various battlepacks, and other things. I bought a couple of the long slim jims and redeemed a gold battlepack. Do you think they are worth they are worth it?
