Pennsylvania grocer Gerrity’s Supermarkets has joined retail grocery cooperative Wakefern Food Corp. Keasbey, N.J.-based Wakefern, parent of the ShopRite supermarket banner, said Monday that Gerrity’s becomes its 48th member. Plans call for Gerrity’s to convert to the cooperative’s The Fresh Grocer banner, with the new store branding to be Gerrity’s The Fresh Grocer. The transition to the new banner over the next few months also will include the addition of Wakefern’s own-brand products, such as the Bowl & Basket and Paperbird labels.
