Organic produce prices vary from month to month and even week to week. Broccoli may cost $4 a bunch this week, and $1.50 the next. Plan your meals according to what's on sale rather than having a fixed menu. Be willing to substitute or do without. Experiment with new vegetables and recipes.
Buy Into a CSA Program
Community-supported agriculture (CSA) programs sell shares to customers. Your money supports a local farm operation and in exchange you get weekly or bi-weekly containers of seasonal fresh fruits and vegetables. Shares start at $300 for the season (about 25 weeks). You could always share the expense with a like-minded friend to cut costs, or ask if the program allows for small monthly payments rather than asking for the whole sum upfront. Some programs also sell half-shares.
Find Coupons
While coupons for organic produce are hard to find, they do exist. Look for them on products' packaging and health magazines. Many companies have discounts you can print directly from their website. Love a special product but can't find a coupon? Contact the company. Many will send you a coupon or discount as a thank you for taking the time to write.
Join a Co-Op
A food cooperative is a group of people that gets together to operate their own store, which sometimes it's also open to the public. Members either pay a share or volunteer a few hours of work a week as payment. Food is ordered from a wholesaler in large quantities (hence the savings) and delivered to a local distribution site (the "store"), from where members pick up their share. Check Cooperative Grocer's website to find a co-op near you or to learn how to start one. Or call the National Cooperative Business Association and ask for a recommendation.
Buy in Bulk
Many organic grains and beans are cheaper when bought straight from the bulk containers. You're saving the company the packaging and advertisement costs and those savings are usually passed on to you. Note that I say "usually." Always do the math and make sure that the savings are worth the trouble. Food sold in bulk must be kept on a dry place, preferably on an air-tight container. If you have to spend a lot of money on special containers to save just a couple of cents, it may not be worth it.
