I just wanted to link to this exciting project, to help ensure they are found by the search engines. The website needs some work (good luck if you can actually work out what the project is!) but this is going to shift mountains.
Another site I'd like to promote is one I found recently selling heritage seeds (also sometimes known as heirloom seeds). I received my first order last week, so I can't report on the quality of the seeds themselves yet, nor the fruit / vegetables grown of course. Still, I was very impressed by the "personal" nature of the site, the order process, and the package I received. Seems like exactly what I was looking for!
