Calculations: 17.5*0.9 - 1 = 14.75 (15 keys is the buyout of the trade)

Total: 15 keys (Rounded to the nearest integer)

Valuing the Mullet at 17.5 keys due to me buying it recently at 17.5 keys (On a side note, the price for the Mullet is semi outdated due to it being about two months old which was when buds were still considered a currency):

Haven't made a suggestion for an unusual in a while, hopefully I'm doing this right.
