I Am Being Charged $538 For A Quantity Of 60

I am being charged $538 for a quantity of 60 pills. Ursodiol is the drug. When I called them the anwer is you must be in the donut hole. I take 2 of these a day and have for almost 20 years. Janice Combs
@ YYYY@YYYY . there is no substitue for this drug as without it I make gallstones. Have not had a gallbladder since I was 26. I am now 73 and afraid to not take this drug.
