2.6 is solely an outlier because the only two ones on the market seem to be getting offers around/above this price range(overpay has been applied on all):

-1 Bud + TS Bills + DP Guadalajara(2.9sh)

-Electrostatic Noir(3.1)

-Steaming Tavish + Vivid Fuka(3.5ish)

-Hellfire Raincatcher(3ish)

-Max's Head(twice)(3)

-Flaming Lantern Chieftain's(2.9ish)

-Cloud 9 Tree(3.1ish)

-PE Shako + 3 Keys(3.3ish)

2.9-3.2 seems fair.
