The only Bandito sale I can trace was for 205 Keys

https://backpack.tf/profiles/76561198062017881#!/compare/1669248000/1669334400

The only Little Buddy sale was a quicksell for 75 Keys

https://backpack.tf/profiles/76561199101442624#!/compare/1666656000/1666915200

That gives us 230 -> 340 -> 400 -> bulk that values the Anger at much less than 400 -> 315 -> 275

While that isn't the best Wrap-a-Khamon sale to use, it provides another sale that supports excluding 400.

Since the Wrap-a-Khamon mini is shaky, 275 - 315 would work here to exclude a low and high sale.
