I would imagine there are lots of people in Rosemary's situation. I remember my Mother-in-law telling me when she lived in a small town in Arkansas how she either had to have her order shipped from Oregon, or drive several hours to a larger city that had a health food store.
I will start out by saying that sometimes your local grocery store carries more than you think they do (and I know, sometimes they really don't!). But, it's worth checking to see if they carry items such as: buckwheat, unhulled barely (though most only carry pearl or pot barley), whole rye flour, brown and wild rice, plain rolled oats, millet or quinoa (these can often be found in the bulk section).
For other items, such as wheat grains, spelt and kamut (grains and flours), gluten free flours, triticale (a wheat/rye hybrid), rye berries, oat groats, millet, quinoa, amaranth, or teff, you generally have to find a reputable whole food supplier.
My personal favorite is Azure Standard. They have delivery routes in 11 states: Oregon, Washington, California, Montana, North Dakota, Minnesota, Idaho, Wyoming, Nebraska, Iowa (hmmm, that's 10, which one am I missing?). They also ship orders to other locations through carriers like FedEx.
Their bulk grains and flours are an unbeatable value, and excellent quality and freshness. I regularly buy their organic oats, spelt grains and flour, kamut flour, barley flour, millet, quinoa, and spelt flakes, in addition to so many other natural grocery items. They are very much worth checking out, especially if you live on or near a delivery route!
For any Canadians, a great resource is Anita's Organic Mill. Grains from the Canadian prairies are freshly ground and packaged in Chilliwack, BC. The prices are reasonable, and it's great to buy more locally whenever possible. Some stores in the Lower Mainland/Vancouver area carry their products, but for many you would either need to go to Chilliwack or have them shipped to you.
One that I've seen advertised many times is Paul's Grains, in Laurel, Iowa. They ship their organic whole grains, cereal grains and flours all over, and have both bulk and regular pricing.
Does anyone else have any online stores to recommend for either whole grains or natural grocery products?
