Roger Corbett, chief executive of Australian retailer Woolworths, has said his company does not expect to lose market share to rival Coles Myer, despite the latter's new fuel deal. John Fletcher, CEO of Coles Myer, which announced yesterday that it has agreed a deal with Royal Dutch/Shell Group which it expects will boost annual sales by around 12% or A$3bn (US$1.95bn),will be hoping to tempt customers away from Woolworths with a discount fuel programme.
