Feeling bad for all the people who upvoted the previous one.

Sale 1: http://backpack.tf/profiles/76561198085032346#!/compare/1468195200/1468368000

Sold for 12 keys + Purple Energy a Hat to Kill For.

This requires a mini: http://backpack.tf/profiles/76561198137519541#!/compare/1471478400/1471564800

Sold for Hot Stabbed to Hell Knife (Well-Worn)

Dedandrei did not have a trade on Outpost for that one, so I don't know what his buyout was. However, according to current unsolds on the classifieds, it is safe to cap at 55 keys.

This puts our sale 1 at 12+55 = 67 keys.

Sale 2: http://backpack.tf/profiles/76561198085032346#!/compare/1468627200/1469059200

1:1'd with Circling Heart Barnstormer (55)

It cannot be used, as this sale was used to price the barnstormer: http://backpack.tf/suggestion/5794556483de6b4fd11f95d1

There are no other usables sales, as you can see on the history: http://backpack.tf/item/562912660

Criticism are obviously welcome!
