Hi, I was wondering if there is anybody that sells TC for steam money.
I know you can't send steam money to anyone, but I could maybe buy something off the market or buy a (cheap) game.
And can I open a thread in the market section for this?

Yeah, not steam money directly. But for other steam items (popularly CS:GO) yes. Make sure you read the market rules before you post though. You wouldn't want your thread closed just because you didn't read over something.

I'm one of those who sell TC for steam wallet codes or steam wallets in items. Also i remember Advens also sells via steam.
