As J-j-jon said in one of his Status Updates on the forums, these need a bit of a bump

Solds at 3.33 or more

http://www.tf2outpost.com/trade/17967908 - Sold almost instantly

http://www.tf2outpost.com/trade/17944478 - .33 ref worth part if you care. 3.66

Some trades to watch (5 ref)

http://www.tf2outpost.com/trade/17896898 - Had an add. Offered 4 ref

http://www.tf2outpost.com/trade/17972785

These are literally the lowest price you can get on Outpost (without parts attached)

Conclusion

I'm sorry for the lack of proof, but if you check Autpot, almost all have parts and are re-named. Nobody selling for 3 ref on Outpost and nobody has been willing to sell at 3 ref for a while, hence no quicksolds at that. Any Extra Proof/Cunter-Proof/Opinions/Tips/Help is all welcome. Thanks for reading. Feedback is always appreciated.
