Simple and quick. I'll definitely use this again, if he's still around when I need to buy a game again.
As long as I still have a bank account, I'll be around. 
Do you sell Team Fortress 2 keys by any chance?
tf2 is free and he does not sell game keys if you read the topic you pick a game and send him the link for it with your email and pay him and then he gifts the game to your email.
He probably means keys to the MannCo crates.
If I'm not mistaken, I would have to gift money to his wallet (minimum $5), which I don't think I can do.
