Supermarket retailer Kmart has revealed plans to create new "store-within-a-store" shopping outlets, through the addition of groceries and 24-hour opening hours to its more traditional smaller-format locations. The company currently operates SuperCenter grocery and general merchandise stores, which range from 140,000ft² to 190,000ft². Within the walls of these Kmart says it will add smaller grocery outlets ranging between 100,000ft² and 140,000ft², and carrying 40,000 food items.
