The last suggestion had people complaining about only one sale, haha.

This being a TC and going to me, it won't go for resale. And it is of course 1:1.

Bought for 10 buds pure, 37 keys, and a Blizzardy Helmet Without A Home.

10 + (37/14 = 2.6) + ???

Bliz HWAH is outdated, so have a mini:

A bought mine for a bud.

http://www.tf2outpost.com/trade/22437540 - Orb Fire Bonnet (outdated)

http://www.tf2outpost.com/trade/22783911 - had b/o at 0.9

http://www.tf2outpost.com/trade/23327354 - had b/o at 0.8

So 0.8-1.0 should be fine.

10 + 2.6 + (0.9 x .9 = 0.8) = 13.4
