About 15 years ago I started on a med that was not covered. It was over $600/month so I went shopping. Got it at an 80% discount thru what seemed to be a Canadian pharmacy on-line. Shipped direct from India and seemed to be the same. No problems. Then GoodRx came around and It was available at a discount of 75% from my local pharmacy. No problems and I felt more confident in the quality, though there was nothing discernible.
The discount varies from one pharmacy to the next and varies over time. The full price had risen slowly and the discount had improved to 95%. But just this week my usual pharmacy changed their 'GoodRx' discount to 55% while others in town raised theirs to 96%. I spoke to my usual pharmacist about cost and he said the store may have a better discount,,,'yes we can give you 94%' Sold.
So the lesson is that you should shop for better prices and understand that it's not all happening in Washington or at the manufacturer. Much of the problem and some solutions are real close to home.
