In addition to grocery/health food stores (feel free to compare prices, coupon, etc. at these conventional locations 😉 ), I have used, or currently use the following sources for our food.
Bountiful Baskets (currently an option in 20 different states), Bountiful Baskets delivers a couple of baskets worth (conventional), or a box (organic) of produce weekly to a drop point, where you pick up your produce. You don’t get to pick what you’ll get, but it’s only $15 or $25 each week depending on the option you choose. This is not a long term commitment, you need to re-order each week that you want to participate. The down side (if you’re not a morning person) is that typically the pickup time is early in the morning. Also, volunteers are needed to help unload and distribute the produce, that starts even earlier.
Azure Standard (I think this is only available in Utah, Wyoming, and South Eastern Idaho), on the other hand is a great source for bulk organic food items. They carry some produce, for instance I commonly order 20# boxes of apples from them. However, for me the main attraction is the 25# to 50# bulk dry goods available at extremely reasonable prices. Other products, like applesauce or olives, are available by the case and often as an order of 3 (as opposed to the case of 12). Once a month your order is delivered to a drop point where you meet the truck to pick up your order.
Local CSA farms are another unconventional source for your produce. Sometimes they are not a lot cheaper than the grocery store, or farmer’s market (also an option), but getting your weekly allotment of produce makes trips to the grocery store a lot less necessary and can save on impulse purchases. An added bonus with this option is that you know your produce is fresh and seasonal. Go ahead and do an internet search for local CSA’s in your area, they are all across the country and I would be surprised if there isn’t one somewhere near you.
Additionally, check to see if there is a co-op in your area. This often involves asking around, co-ops may not invest time in a web site, especially if they are well established.
Sometimes Amazon or other online sources will have a good price too.
Additionally, warehouse stores like Costco can be good supplemental sources for food. As long as you’re not an impulse shopper that will end up spending more than you save. 😉
And of course, compare the prices in local stores with your options when ordering from other sources.
