In the one positive earnings report from the holiday period for an English-language bookselling chain, Canada’s dominant Indigo said that the same-store superstore sales rose 3.4 percent for the quarter ending December 26, while their smaller format stores were down 1.6 percent. Overall sales rose $10.2 million or 3 percent to $340.2 million (CA). Net after-tax earnings of $34.5 million were 29 percent higher than a year ago. But Indigo still suffers from competition with Amazon online, with online sales declining 2.7 percent to $29.3 million.Release
