Sale 5) Sold for a Haunted Ghosts Ze Goggles

https://backpack.tf/profiles/76561198003824273#!/compare/1529539200/1529625600

This would be better used there, as its only sale is for an Electrostatic Casemaker, so it can have a range.

Sale 6) Sold for a bot's quickbuy order for 41 Keys + 6 Refined

https://backpack.tf/profiles/76561198057292675#!/compare/1529625600/1529712000

Including 52 Keys because had I resuggested when the Law suggestion was first made, the sale would've been in-date.

The sale also would've been in-date had the previous suggestion been accepted.
