CVS Pharmacy must depend on prescription drug sales to stay in business, but Wal-Mart doesn't must add a tremendous markup to the medications they sell. When all factors are thought, however, I would need to say that the prices charged at CVS Pharmacy and Rite Aid Pharmacy are very comparable. Most drugs need to be stored at exact temperatures, so one in the things pharmacists learn in pharmaceutical quality training will be the necessary steps to help keep the facilities clean and in compliance with regulations.
