Resuggesting for a smaller range as 33 and 14 are outliers (i had that feeling but my second suggestion so was really confused on what to price this at lol)

Second ever suggestion (First one didn't go so well as I had things to learn and the Razor Cut is a bit hard to price because compare is annoying ahhh)

Bought for 13 keys 36 ref rounded to 14 keys.

Sold for a Blizzardy Storm Desert Marauder (17) + 4 keys and a sniper cosmetic = 21 keys

Traded for a Misty Skull Handyman's Handle + 3 tickets a munch of ref and 1 key.

[Misty Skull mini (Sold for a DBD Physician's Protector + around 7 in items) (another sold for a Tesla Coil Rebel Rouser priced 26)]

So we have a sale of 35 and a sale of 26 so we will give it a mini of 30.5.

So 30 keys 18 ref and 3 tickets (51 ref) and a key = about 33.

Last sale was sold for 19 keys pure

So the sales we have are 14,21,33 and 19.
