Tried to buy seeds. Shopping cart just defaults to nothing. Tried to contact them. Impossible. Capcha required (the captcha is invisible, so much for that idea.) So as far as I'm concerned, Delicious Seeds can F Off and I'll find a supplier that understands online shopping.
Great Lakes Genetics, JBC seeds, and DC seed exchange are a couple good ones. Not sure about payment options for the latter two, but GLG takes blank usps money orders or cash by mail. It is a bit of a hassle, but he includes some of his own seeds as freebies with each order.
