Why do not you rather sell the cards directly on Steam and get keys that way?
Your top 25 trading cards (no foil) are valued 4usd, more than the value of a key.
Well I wouldn't let him take the top 25 you see. I would make sure the trade is fair, the reason I don't just sell items on Steam is due to the simple fact that they tax everything so I don't get all the money.
1 CS:GO Huntsman Key for 40 Random Cards. You may pick cards. Everything is fine except L4D2 / Dino D-Day / CS:GO / L4D2 / Awesomenauts. So yeah, you may as well pick all cards valued 5-7 eurocents, I don't really care. I look for quantity over quality.
Offer me.
