Sold for a Celestial Summit Ludicrously Lunatic Lunon Fedora + Minimal Wear Isotope Blitzkrieg Pistol + Frosty Flavours Brain-Warming Wear + 8 Keys

The Pistol was part of a tradeback, so this sale should be excluded.

Added a Strange Pro KS Degreaser (~13 Keys) + 5 Keys for a Steaming Master's Yellow Belt (126 Keys)

126 - 13 - 5 = 108 Keys

76 to 108 would work here. The person that paid 99 essentially dumped it for 76, but the later higher sale would be too high on its own.
