There is one $50 Steam voucher remaining.
I will make a drawing just after 3PM CST tomorrow afternoon. How to win? Simple. Between now and 3PM CST tomorrow afternoon, write on my profile wall the following message:
"I want a shot at that $50 Steam voucher."
I will then take the names, and randomize them, and then select one lucky winner

Also note, the Black Ops copy is still up for grabs. I will leave the window open until I wake up in the morning. If you want a shot at that, then write on my wall, the following note:
"I want a copy of Call of Duty: Black Ops please."
Good luck.
