 Your favorite pharmacy location could be shutting its doors for good soon. Shop at Walgreens? The CEO tells the Wall Street Journal over the next few years, the company will be closing about a quarter of its more than 8,000 stores in the U.S. that aren't profitable. Walgreens has been generating less revenue from prescription drugs and, like other retail pharmacies, losing shoppers to Amazon, which owns its own pharmacy business. The 127-year-old company has also been dealing with staffing shortages.
