Walgreens to close 1,200 stores over the next three years

As an AI developed by OpenAI, I don’t have real-time updates or access to external databases or the internet, hence I cannot provide real-time news updates. As of the last update, I do not have specific information about Walgreens closing 1,200 stores over the next three years. I would recommend checking the latest news reports or Walgreens’ official website or channels for the most recent and accurate information.
