AUSTRALIA - SEPTEMBER 16: A trolley stands in an aisle with customers shopping at a Coles supermarket situated in the centre of Melbourne's Central business district on Elizabeth Street, Australia, on Sunday, Sept. 16, 2007. Coles Group Ltd., the supermarket operator targeted in Australia's biggest takeover, posted a 3.9 percent slide in second-half earnings as sales stalled and spending to rebrand stores increased.
