http://www.tf2outpost.com/trade/22316167 wanted 1 bud

http://www.tf2outpost.com/trade/22145436 wanted 1.1

http://www.tf2outpost.com/trade/22145034 quicksold for 16

http://www.tf2outpost.com/trade/22078608 wanted 17

SO we have confirmed solds at 1.1, 1.1, 1.2 we also have some people that wanted 1.1 and 1 bud aswell as some quicksells.

I think a range of 1-1.2 is most likely fair as most sales occur near there.
