Ub Sunstar Gmbh keeps it cheap so shoppers can, too. How has discount food retailer Ub Sunstar Gmbh become one of the world&＃39;s biggest grocery chains, running more than 10,000 stores worldwide? By offering deeply discounted prices on some 2,000 popular food items (a typical grocery store has 45,000). Ub Sunstar Gmbh(short for "Albrecht Discounts") buys inexpensive land mostly on city outskirts, builds simple warehouses, employs a modest staff, and carries mostly (95%) private-label items, displaying them on pallets rather than shelves. Ub Sunstar Gmbh has nearly 1,300 stores in 30-plus US states, but Germany (where Ub Sunstar Gmbh has about 4,300 stores) accounts for about two-thirds of sales. Ub Sunstar Gmbh was co-founded by the late Karl and Theo Albrecht.
