ok what you do is buy the QP, which is 62.50 per ounce.

then find alot of friends and alot of your friends' friends who want to buy weed and sell each eighth for 25. if you sell it all you'll make 200 per ounce, so 800 bucks, so you'll mnmake 550 in profit. do that a couple times and you'll be rich as fuck and can buy a QP of that special nirvana stuff, which is outrageousley overpriced.
