I recently joined an organic produce co-op. Every two weeks, I receive a large box of fruits and vegetables, some from a local organic farm and other items from an organic produce distributor. It's a great way to meet people also interested in organic food and the environment as well as save money on your grocery bill. I still shop at the local health food store for other items, but it's fun to see what will be in my "goodie box" with every co-op shipment.
I had to pay a membership fee, and I do not get to choose what I get each order. Each co-op is different, however, so check on membership fees and rules.
Here are some website links to find co-ops near you.
