Shoppers are increasingly using digital tools to research their grocery purchases before and during their trips to a store, according to a new survey of 570 consumers from KSC Kreate, Hollywood, Fla. Before going to the store, 36% of consumers research grocery purchases online, most often to find coupons, competitor pricing and recipe ideas. One in three grocery shoppers use a mobile device in-store to look up recipe ideas, coupons and other info.
