[H] Amazon GC, Steam Wallet, keys [W] Counter Strike Global Offensive (full), Battlefield 3

Title says it all, I'll offer my Amazon GCs or Steam Wallet (which I can use to buy keys) for your CS:GO or BF3.

Note: I can use my Steam Wallet to buy Dota2/TF2/CSGO keys, but I'd prefer trading with my Amazon GC if possible.
