About Us

Each Co-op has their own version of how the local Co-ops started, but really all stores started off the same way.  A group of neighbors and farmers got together and decided to pool their buying power and as a result, the local Co-ops was born.

Small groups held several meetings and decided to form their own businesses,

In the beginning years, the main activities of the groups consisted of buying various goods in large quantities and selling these items to their members at cost plus the transportation charges.
