This may be lacking in moral, but sure not in price...

Recent sales:

http://www.tf2outpost.com/trade/25000641 4.66 ref

http://www.tf2outpost.com/trade/24954693 5 ref (Althought the item history on it hasn't changed, since his last backpack scan he gained 5 ref in a line, and it is not in his BP)

4 ref quickbuyers:

With no sellers and several quickbuyers, 4 ref has become too low, and with sales at 4.66 and 5 ref, and with a bit of uncertainty over the 5 ref sale, going conservatively with 4.66 to 5.
