Help, I look for the skins of the Wal Mart and Circle K stores

Goodnight.
I’m looking for help to get the lancer skins, exclusive to Circle K and Wal Mart, since I’ve been looking for them for quite some time and can’t find them, can you help me?
I have drink codes.

Best bet if you cant find them locally, you can buy the codes off ebay.

You realize you can buy any Rockstar at Walmart and if you go to the self-checkout a code is printed on your receipt. I’ve done it a few times. You dont need the Gears of War specific cans in order to get the codes.
