CVS Caremark leads With nearly 6,300 CVS/pharmacy locations and 56 specialty pharmacy stores from coast to coast, we operate more stores than any other U.S. drugstore chain. More than 60 percent are freestanding, making it "CVS easy" for customers to fill prescriptions, replenish the medicine cabinet, or stop in to consult with one of our beauty advisors. With free time in such short supply these days, 60 percent of our locations offer drive-thru pharmacies and 72 percent provide the convenience of 24-hour or extended-hours drugstores.
