Going to update this price after 6 months.

Firstly, the sellers on outpost :

http://www.tf2outpost.com/trade/19204187 B/O 3.5-4 buds

http://www.tf2outpost.com/trade/18795199 B/O 3 buds or 3.5 in unusuals

Sales:

1) http://www.tf2outpost.com/trade/18394244 Sold for green fetti conjurer's and a bud pure - 1.8 + 1 = 2.8 buds

So overall : 1.8 x 0.9 + 1 = 2.62

Hat price is not outdated

2) http://www.tf2outpost.com/trade/18175596 Sold for KaW Hermes - unpriced

3) http://www.tf2outpost.com/trade/16370315 Sold for Aces high glasgow helm + 3 keys as stated
