David Dillon, chief executive of US grocer Kroger, has said the retailer will concentrate its efforts on pushing sales at existing stores, rather than seek to enter new markets or make acquisitions. Speaking at the company’s AGM, Dillon said even though several small chains had been snapped up in recent years, acquisitions are definitely not part of the company’s growth plan for the time being. Instead, its loyalty card will become a key focus, particularly through encouraging cardholders to shop more often.
