Some counter proof to myself:

http://www.tf2outpost.com/trade/10565206 - 1.44

http://www.tf2outpost.com/trade/10522849- asks for 1.66, unsold

http://bazaar.tf/trade/209733 - asks for 1.66, unsold

http://bazaar.tf/trade/161561 - selling a few for 1.33 (unsure if still active, trade is bumped but I think it is hourly auto-bump?)

Notes:

I pretty much went through a good 70% of those selling on outpost.

None on classified listings as far as I can see.

Bazarr.tf is also very sparse on people selling. Most are months old and asking for 2 ref + or are hat exchange trades.

There are some 1.33 offer on outpost, but from what I can see most are hidden / beaten by others offering more.
