Express Script staff do not seem to understand the importance of insulin, every time I have ordered it over the past year it is always a problem but today when I called I got transferred twice to the wrong people and then placed on hold so long I just hung up. I have been dissatisfied since I have been with them, all of 2022 and into 2023 same. I do not recommend Express Script to anyone or any company looking to do business with them. I pray they read this and handle business
