SACRAMENTO, Calif. — To make a long, expensive story short, my pharmacy recently made a mistake on a monthly prescription with a new insurance company and charged me $200 for what used to be a $20 prescription bill. 

Several phone calls and headaches later, it got resolved, but it got me thinking… how often does this happen? Now, I'm on a mission to save you money when it comes to the drugstore and your medications.
