Mark is well known around these parts for providing good quality genetics at low prices. Here is his site and contact info:

HIs site is out of date and currently he has many more strains than those listed, so contact him and ask him what is available. It usually works out to about a buck a bean, and he also has autos which are slighty more, and he always tosses in extras. He also ships first, and you send the money after you have gotten the seeds, so what could be better than that? I highly recommend Mark for good genetics at an amazing price from an honest seller.

FYI - he only ships to the USA (this includes Canada or anywhere not actually in the United States)
