The best produce in the WSM!
Pros: They try to keep things local and organic; they take orders over email and have it ready for you the following day; the produce is the freshest available at the WSM (their stuff takes forever to go bad--crisp things stay crisp and fresh); they have amazing sales (just got 20 lbs of tomatoes for $8); the owners are incredibly nice and helpful (I was missing an item in an order and they called me and offered to drive to my house to deliver it); their prices are generally cheaper than what I get for the same/lower quality at various grocery stores in the area (try to find super fresh Ohio produce at the grocery store for less and you'll be searching forever).
Potential Cons: They close early on Saturday (3pm--I'm ok with it, but it's something folks might want to know); their stuff might cost a little more than other WSM vendors (you get what you pay for and I've had things spoil in as little as one day from other vendors).
These folks are the model for great WSM vendors!
