here is how the market works.
someone grows 10 pounds of herb, he could either sell it by the gram, 448 grams in a pound, so he would have to make 448 indivdual sales just to sale one pound doing by the gram...

OR he could unload it all at once... but obviously the larger amount you buy the more of a volume discount a person gets on the street.
So the guy who grew the 10 lbs he probably will sell off 1lb at a time for 3,000.00$ a pound or let the whole ten pack go for 20 grand.
then somene splits that up.
On the street small time growers buy ounces and then hustle grams and a couple 8ths to make money..

the next fish above that person might by quater pounds then hustle ounces to people.

that guy gets his herb from the seller who sells pounds.. the guy who sells pounds doesn't fuck with selling grams... chump change to them

the guy who gets pounds gets them from the grower.
in every transaction the price increases.
