Formed in 1973, PSFC has grown to include over 17,000 members. The PSFC business model requires each of its adult members to contribute 2 hours and 45 minutes of work every four weeks, and that no member share a household with a non-member. In exchange, active members may shop at the store. The store sells a variety of foods and household goods, some environmentally friendly products, at a 21% markup over the wholesale price (compared to 26-100% at a supermarket). An additional temporary 4% markup was implemented in October 2020 to help the co-op offset the financial impacts of COVID-19. Members facing financial hardship may opt-out. The savings are possible because labor is contributed by its members. PSFC operates as a New York state cooperative corporation.
