[H] GTA IV & San Andreas, L4D2, CS [W] Good Offers

Don't wanna be offensive, but would you like any of coupons, I got? http://steamcommunity.com/profiles/76561197980029003/inventory/#753_0
If you are interested in any, I would like to exchange for CS (it is an original one, right?)

Cogs and Portal 1 for Left 4 Dead 2?

L4D2 + CS + San Andreas for Dead Island EU Key?
