Well they said 13 lbs where sold in between the 3 locations so let's reduce that to approximately 10lbs right. we can say average 2 days for the stores open (3+1+1=5/3=1.8 days). So, for every 3 locations open for 2 days sells 10lbs of pot with 365/2=182 x 10lbs= 1820lbs sold (again for every 3 stores annually) 

Take the1820lbs x $10,000= ?

I can see big numbers!
