Greenway only sells 1/8ths and larger, 1/8th of Erkel was $60. They do sell what they call "Old School" which is pretty low grade for pretty cheap.
SCPC sells grams, 1/16ths, 1/8ths, and up. 1/8th runs between $55-60 , I definitely think SCPC has high grade strains as they claim.
Oz where pretty pricey at SCPC with the cheapest running at $450, you don't get the dealer buy more pay less discount.
