I filled a prescription last year for $10 dollars. I am inconsistent with the use of this as it is for acne and I am lazy. Had the prescription refilled and they tried to charge me $30. I called my insurance and was told the first time it was submitted as a 30 day supply and the second time it was submitted as a 90 day supply. Called Walgreens to have it set back to a 30 day supply and was told that because I don't fill the prescription every month they are charging me for a 90 day supply for the exact same amount of medicine. My husband has already left Walgreens due to their bad billing practices, he was charged for 3 30 day refills instead of 1 90 day because they didn't have a bottle large enough to hold the 90 day supply and had to put it in three bottles, and I am now going to leave them as well. I will also report them to my insurance for fraud. It makes absolutely no sense that the exact same amount of medicine can be charged as a 30 or 90 day supply depending on how often I fill it, which to be honest is once or twice a year, I am surprised they didn't try to charge me for a 12 month supply!
