Whats Canna butter worth

so i have a patient that would like to trade for my extra mj coconut oil.
whats it worth?
my dosage can range from 2-3 grams per when i make it into edibles.
1g of trim/larf/leaf = 1g of coconut oil. aprox.

About tree fiddy.

I use an ounce of bud and simmer in a crock pot. Usually get 2 sticks of butter all said and done. A few of my buddies make it but, they don't use bud. Depends on what's in it I guess.

A-How much is your trim worth for a pound?
B-How much does the coconut oil cost to do a pound of trim?
C-Add a reasonable amt. for your time
Add A, B, & C, divide by 150 and this is the cost per dose

A = ~50$
B= $40
C $50

gives me .90$ per dose or 30$ per 100 grams.
which is the same number i got doing the math my way. haha
