I know U want it 2. E-Bay usually won't sell U an expired code unless they disclaim as such, It probably won't work but (Risk/Reward) factor is worth what to U - 2 bucks (free Shipping), I'd take the chance, but over $5 - not worth the most likely result. Make sure U pre-order Halo Ce:a because w/pre-order U get the "Grunt Funeral" Skull which will only be available that way.
