Fraser Valley Hemp They seem to have a decent selection of strains, but I recommend turning off "Auto Load Images" before you browse their site. You don't need the graphics, and throughput off their server is typically lousy.
HempNation They're permanently out of the seed business, but the owner Chris Clay has a great deal of information relating to his current Canadian Constitutional Challenge and pending legal case(s). Have you bought your victory bond yet?
Amsterdam AlohaAloha has a nice shopping-cart interface for you to browse their inventory. They ship worldwide.
Marc Emery Direct Seed Catalog(HempBC) This was the first seed bank I discovered, and I have been extremely satisified. Although they do not ship to the U.S. (other than California & Arizona), they work with an independent distributor who will ship to the states.
[TAC] Seed Bank Catalog Run by the TAC crew out of Switzerland. They have a small selection, but fair prices. They ship to EU and Canada.
GanjaLand/a.k.a. Bonhomme/a.k.a. BIDS Notoriously the worst seedbank online. The owner of this operation, Duane Lewis, has asked me to remove my negative comments about his seed bank, citing overwhelming business and start-up confusion as the cause of customer dispair. He said he was going to post to a.d.p.c. and explain the situation, but I have yet to see the post.
Sacred Herb Located in downtown Victoria, B.C. The store's owner, Ian Hunter, is very involved in local politics and defending the rights of Hempsters everywhere. They don't ship outside of Canada, but they welcome anyone to their retail store.
Sagarmatha A wide variety of seeds. All prices in Dutch Guilders. No shipping to North America or France.
Positronics Dutch Passion Sensei Seed Bank All three banks are hosted on the KAWUMM site. Not a graphically intense catalog. All prices are in DM. They DO NOT ship outside of EU. Sensei actually has the registered trademark on most common strain names.
Serious Seeds A beautiful site. They sell their seeds via mail order and retail through a number of outlets in Europe. Prices are all in Dutch Guilders and they ship only to EU.
Seeds 'R' Us A thin selection of seeds, but what they sell is "available nowhere else". They ship worldwide.
