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