proof would be nice

It need a range. I owned one for 2.33 1 month ago and sold it for 2.66.

Actual proof would be nice sounds like an easy upvote if you had proof. Otherwise I am remaining neutral.

This one also sold for a key outside outpost: http://www.tf2outpost.com/trade/5749767

I also could find a lot people offering below 2,66. All got rejected (a few lucky ones as exception).

Couldn't find any for less than a key: http://www.tf2outpost.com/search/48392535
