Recommend me a good seed site?

Or convince me that there really isn’t a difference. I’d like to get an herb garden going again, but the local Wal-Mart doesn’t have any more seeds. Does anyone know of any fantastic websites to buy seeds from?

Herbs

Two I like, because they have stuff you won’t find at Wal-Mart:

Hirt’s Gardens

Cook’s Garden

My favorite, because of their extensive variety, great germination rates, in-depth knowledge they’re willing to share, and because the owner still answers the phone himself 9 times out of 10: http://www.horizonherbs.com/ Yes, their focus is on medicinals, but they also have much of the yummy and pretty stuff.
