Sale 3:

Sold for Miami Nights Cloud Crasher + ~8 keys in items

http://www.tf2outpost.com/trade/28426800 - B/O of 22

Seller: http://backpack.tf/profiles/76561198103634507#!/compare/1472428800/1475020800

Buyer: http://backpack.tf/profiles/76561198204192480#!/compare/1474761600/1475020800

Couldn’t get a proper mini on the Cloud Crasher. It would have to be less than 14 keys to affect this sale’s value, however, and I doubt that would happen.
