GoodRX has consistently had lower prices for both myself and my wife's prescriptions. Only downside is that the best prices may require getting the scripts from more than on pharmacy. Two of my wife's prescriptions are cheapest at Winn-Dixie pharmacy and two others are cheaper at Walgreens. They are close to each other so it is no big deal.
Tip for consumers: Make sure to compare the pharmacy prices rather than just one.
