SuperValu is a supermarket chain that operates on the island of Ireland. SuperValu is operated as a symbol group; each store is independently owned, with store owners using the SuperValu format and selling the chain’s own brand products. SuperValu outlets tend to be larger than the convenience shop formats used by many other symbol group retailers such as Centra, Gala and Spar, and the larger SuperValu stores are on a par with full-service supermarkets. Their main competitors are Dunnes Stores and Tesco.
