Because of high shipping costs, it can be less expensive to buy grains, like wheat berries, rye, pearl barley, and spelt in bulk from local stores. Try to arrange to buy bags of whole grains for cost plus 10%. You may be asked to pay in advance. For grains you cannot obtain locally, I provide a list of online companies selling grains in bulk to the consumer market. Several of these companies sell grains to people who buy bulk grains as the part of their religious beliefs. Many of these suppliers sell organic grain.
