Well why would someone go for 4 keys if you stated you could sell it for 3? xD
This game is pretty cheap, and few times on bundled. I think is not even worth for 1 keys. I suggest to trade with other games.
You should listen to this guy. Most of the time you should use g2a to know what the Price should be, approximately. Good luck trading!
