H: Mafia 2 pre-order code (steam) W: steam gift, xbla games

[r1p]

Hello
I have one pre-order key for Mafia 2 (PC) so it's probably steam code. It's one of this keys:

-Vegas Pack
-War Hero Pack
-Renegade Pack
-Geaser Pack

I think it's not possible to check this code before redeem.

I want:

Steam Gift offers
Steam keys
XBLA games
Microsoft Points

EDIT: gone
