Request MW3 CD Key Steam

Soooo, right now I don't have 60$ and I can't buy the game online. So, could anybody get me a cd key for mw3 on steam? I would greatly appreciate it if you can. Thanks. c:
I can also do some trades. (Depending on what game you want)

There are cd key sites out there that sells it for 17-18 bucks.

Like I said, I can't pay online.
