Discount chain Aldi celebrated the opening of its 58th store in Ireland last week. The new store, on the outskirts of Cobh, Co Cork, is among 14 shops the German business is set to open over the next year. A spokesman for the company said it had seen a considerable increase in customer numbers in Ireland as the credit crunch sets in. The competition authority now estimates Aldi has a 5% share in the Irish market.
