Only 2 of these on outpost without killstreaks. 1 wants offers, the other wants 5 keys and ignores every single offer and friend request

Yesterday one sold for 11.11 usd, I don't know how much that is in keys.

But if you receive about 2 dollars per key sold on the market, it would cost you over 5 keys to buy one.

All credit goes to The Real SSJ3 for providing the proof.
