What all do they have? Very expensive?

They have many varieties of heirloom tomatoes - the varieties change every week as they deliever new ones on Fridays. I think they are $3 each - about the same as anywhere.
As for herbs it looks like a lot of varieties - oregano, hot and spicy oregano, golden oregano, thyme - lemon, english and mother, mints - orange, peppermint, spearmint, chocolate, pineapple etc - and like that for all the herbs - several varieites of each. I think they are $3/each too.
I did notice that each store has different varieties of tomaatoes so if you are looking for particular varieites one store may have it and not the other - but there are lots to choose from. They also had some neat tomatoes to grow in containers.
