seedsdirect has Blue Haze, but not purple. Heavans Stairway didn't have it either. You can try Marc Emery, but I do not know enough about him to recommend him.
Marc Emery isnt that great of a connection, the best bet is as BPP said and go with the blue haze that seedsdirect has they are very trustworthy and Gypsy Nivana is a great guy for help!! good luck on your search Budguy™
