A retailers' cooperative is a type of cooperative which employs economies of scale on behalf of its retailer members. Retailers' cooperatives use their purchasing power to acquire discounts from manufacturers and often share marketing expenses. A retailers' cooperative is essentially a group of independently owned businesses that pool their resources to purchase in bulk, usually by establishing a central buying organization, and engage in joint promotion efforts. It is common for locally owned grocery stores, hardware stores, and pharmacies to participate in retailers' cooperatives.
