Costco takes battle to sell alcohol in SA to Supreme Court

US RETAIL giant Costco is trying to broaden the supermarket war to another front, taking its battle to sell alcohol in SA to the Supreme Court. The bulk-buy retailer has appealed to the state’s highest court for a licence to sell liquor at its Kilburn outlet. But the Australian Hotels Association is warning any such move — if approved — will set a dangerous precedent and be another stake in the heart of small alcohol retailers and SA wine producers, who are struggling to make a profit.
