I had previously recommended a company called Heirloom Veggie Seeds/Get Seeds to purchase heirloom seeds from. I no longer recommend them as it has been 6 weeks since I placed my order and paid for my seeds. I have not received my seeds, nor am I able to get a response from the company as to why I haven't received them. So buyer beware.
Update: I received my seeds yesterday and finally got an email from the company. I am still not sure that I would recommend ordering as they take so long, but at least they are not thieves or dishonest. They simply are slow, but I am very happy with my order.
