Range is too large for me

http://www.tf2outpost.com/trade/9677952- claims to have bought it for 4 pure, considering offers over 4 pure, wants 4.5 out of his hat

http://www.tf2outpost.com/trade/9575702 - 4 pure c/o

http://www.tf2outpost.com/trade/9568058 - b/o of 4 buds + 10 keys

http://www.tf2outpost.com/trade/9274462 - supposedly offered 4.5 buds

http://www.tf2outpost.com/trade/9945986 - hoping for 5 buds, minimum of 4 buds

Not too sure of the range as it is only 2 of them exist. I will gladly accept suggestions for the range. I had 3.9 based on 4 pure might take some time, but if you wait long enough, you might even get 4.5, which is the highend
