Many prescriptions go unfilled because people can’t afford to pay for them. But those prescriptions may be more affordable than you think. In recent years, major discount stores, and also some grocers, have started generic drug programs that will allow you to buy a 30-day supply of commonly used medications for just $4. Keep in mind that if you’re insured, you may pay more or less under these programs, depending on your health plan coverage. So always ask before ordering. For a rundown of the major $4 generic drug programs, including WalMart, Sam’s Club, Target and Kroger stores (presumably including King Soopers and City Market), read the full story on our sister site, Living on the Cheap.
