(Woonsocket, RI) -- Woonsocket-based CVS is purchasing Aetna insurance for sixty-nine billion dollars, the "Washington Post" reports. People familiar with the deal say it could possibly rein in the high cost of healthcare. It might also transform standalone pharmacy storefronts into community medical hubs for primary care and basic medical procedures. If regulators sign off on the mega-merger, CVS would provide a broad range of health services to the twenty-two million Aetna medical members inside the nationwide chain of pharmacies and walk-in clinics.
