Staples reported weak Q4 earnings on Friday, posting a net loss of $260.4 million or 41 cents per share. Sales at the office supply retailer chain were down 3.7 percent, hit by the strong dollar and lack of product demand. Revenue fell to $5.66 billion, down from last year's $5.87 billion. Profits did come in slightly above analyst estimates at 31 cents per share but the company forecast a continued sales decline for the coming year. Staples is still waiting on regulatory approval for its $6.3 billion deal to buy office depot. The merge will create a single office supply superstore for the U.S. market. Regulators blocked a merger of the same companies back in 1997.
