The purpose of this new entity was to collectively pool their purchasing power in order to buy material at the lowest available price. Furthermore, all "net" profits of this entity would be rebated back to each owner in the form of patronage dividend. Eighty years later, PRSCO is a nationally recognized regional cooperative with over 120 stockholder dealers consisting of over 175 locations.
