sacredseed.com has their lovely little shop just off Yonge st.

It all depends what you want... Nirvana Standard seeds are IMO a fantastic deal, you can get them on seedboutique.com and even cheaper on seedbay.

But if you like to walk in and browse,the shops are sweet. Or if you're paranoid. Be warned they only take cash in my experience... bring a lot!

I got my first good seeds at a shop, but since Toronto is like 7 hours away from my house now I just do mail-order.
