Key of "Just Cause 2"/"Mafia 2"/"Fallout: New Vegas" for "Resident Evil 5" on Steam

Hi guys!! ^^
I wanted to buy RE5 in store, but there isn't a Steam key, so I want to make a trade:
one of you guys adds me on Steam and tells me if he/she prefers a unused Steam key of "Just Cause 2", "Mafia 2" or "Fallout: New Vegas" and he/she gives me "Resident Evil 5" on Steam as gift.

NOTE: tomorrow I can buy the key, but remember: first I want to be sure that you guys have the game.

Thanks,
