http://www.tf2outpost.com/trade/23623443 - Buying for 0.11 each.

http://www.tf2outpost.com/trade/23670427 - Buying for 0.11 each...again.

http://www.tf2outpost.com/trade/23359601 - Buying for 0.11 each... once again.

Sadly most expired, so its hard to find enough proof. I know most of them are buying for 0.11 and selling for 0.33/0.66 but i find 0.33-0.66 a more of a balanced price.
