Seen so many bought for 2 keys on outpost. Downvote

Agreed, I managed to buy a Strange Degreaser with Allies Extinguished and Projectiles Reflected for 7 ref. I think its quite acceptable

I think using refined as a range is good. Offers aren't exceeding 2 keys, almost every seller wants 2 keys and the suggester has been able to buy for 5 refined without having to wait long. You have my upvote. Also some people still value 2 keys as 5.33 refined.

e.g. http://www.tf2outpost.com/trade/6666932

I'll upvote. 2 keys is still possible but people are extremely reluctant to sell their keys. I see more people willing to spend 2 keys in metal for the degreaser than 2 keys pure.

I think 5-6 ref is better than only 2 keys upvote.

These very easily sell at 2 keys. Downvote.
