[H] Copy of killing floor [W] 2 keys of any type (CSGO, TF2)

Wrong site, you want SteamTrades.

copy of KF worth 2 keys? lmao stupid trade offer.

Go back to your trading site.

<banhammer incoming>

1. Wrong site.
2. You'll be lucky if you get half of that for the game.

You should probably try a better trade, like [H] KF [W] 1key+offers, because 2keys is way expensive for a game like KF, i doubt you will get any good tradeoffer, you might have some scamm offers tough, and try other sites for this trades, this network has 1 specially for trades, check it out, SteamTrades.
Peace & Love ma boy
