[H] Coupons [W] TF2 items, games, or better coupons

I have many coupons which include:

-33% Valve title
-50% Strongbad's Cool Game for Attractive People: Season 1
-33% Dungeon Siege III
-50% Dungeons Of Dredmor
-50% Grand Theft Auto IV complete pack
-50% Section 8 Prejudice
-25% Valve title
-66% Prototype

As I said, I am looking mostly for TF2 items but games are appreciated. I am also fine with trading for better coupons. Thanks.
