Consider joining a CSA.
CSA (Community Supported Agriculture) members buy a share feeding about four and averaging $500 in a farm's produce for the season (usually 22 weeks). According to Erin Barnett, director of Local Harvest, “CSAs are not always cheaper on every item, but for what you're getting, you're paying much less than in the grocery store. Shelf life is longer and yields higher.” Plus, your food dollars stay in your community. Food co-ops usually sell reasonably priced locally grown produce.
