Serving the Princeton University Student, Faculty, Staff and Community since 1905. The Princeton University Store is a not-for-profit cooperative society whose members share in the profits. As a co-op, it operates differently from an ordinary corporation. It is governed by a Board of Trustees made up of students, faculty, administrators, and alumni, and instead of paying dividends to Wall Street shareholders it gives discounts to its members. Members receive a 10% discount on nearly everything in the store
