4 trades with it in their wishlist. Two are not buying, the other 2 are 1:1 trades of items worth ~ 2 refined

http://www.tf2outpost.com/trade/4569553- A lower comment here shows that when this fellow WAS buying, it was for less than 2.22 ref. He successfully bought 2 and stopped buying since.

Warehouse has the genuine shaman for 8,755 credits- a little under 2 refined's worth given its 4,500 credit refined metals. It is overstocked.
