also untrace

There are no usable sales that i can find on the swagmans, but the range between buyorders and sell orders is marginal compared to the price of the kabuto

Using buyorder of 365 at the time of sale https://imgur.com/a/HU93Y29

Total:

1800 + 443 + 365 = 2608 rounding to 2600

Will update suggestion if a usable sales comes up for the swagmans
