The Park Slope Food Coop, founded 1973, is the largest wholly member-owned and operated food coop in the country. In exchange for 2 3/4 hours of work every four weeks you can save up to 20% - 40% off your grocery bill. The Coop is owned and operated by its members and is therefore, responsive to the membership rather than to the companies trying to sell their products. We are located at 782 Union Street, Brooklyn, New York 11215 , (718) 622-0560
