A customer pushes a shopping cart in a car park outside a Sainsbury's supermarket store, operated by J Sainsbury Plc, in Crayford, U.K., on Monday, July 7, 2014. Sainsbury said last month that it expects same-store sales growth to resume later this year after nine years of unbroken growth was ended with two quarters of decline.
