It all comes down to two variables: inflation and quality of the product. As minimum wage is increased in the US, the cost of living goes up as does the price for goods (gas is going up, milk is going up, and so are utilities). It's a fact of life. Likewise, if you want quality pot, most people are going to make you pay for it. Also, importers of bud are able to charge more because the price of the US dollar in comparision to other countries' monies has declined in recent years as our great (sarcasim) leaders keep sinking us further and further into debt with other nations.

300-400 for kind bud

400-600 for kush, haze, Soma, and NYC sour
