From all the movies documentaries and internet reading I would compare profits of a dispenary to the profits of a walmart they make a tremendous take. Imagine if you will being able to cop a lb of anything from swagg @ like $100lb to humble's finest for like no more then a 1000. Then breakdown 448gs roughly a pound divide by 16oz @ average price 250to300 a zip=that's right way more then you paid for it.
"They must have had 2-300 pounds in there."
let's just say they had 50 pounds all high grade no swagg or shake oz's 50 pounds all buds sold half in zips(300per oz) and half in g's and 1/8's. 10lbs and sold in 15to20$GRAMS 448*10*20.00$=89,600 15lbs broke down into 50$ eigths 448gs/3.5=128 eigths per pound 6400.00lbs if sold in all 50.00$ 1/8ths 6400.00*15lbs=96,000 total for 25lbs retail roughly 185,600$. 25lbs =400oz*300$=120,000$
these numbers would drop by half if marijuana was legal for everybody over 21 not just medical use
or just say if they made 10,000 a day for 30days =300,000$*3months=900,000$.
