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.
