https://backpack.tf/profiles/76561198065283212#!/compare/1642636800/1642723200 - 37 Keys

37 - 40 would work for the Mullet's price, which averages to 38.5 Keys

That means that the sale progression here is 40 -> 35 -> 24 (supposedly 40) -> 29.5 -> 35. While there is a buyer at 35 Keys, it's only 1 buyer who didn't have a listing a week ago.

Taking 30-40 here
