On July 5th, 2021, I went to Walgreen's Pharmacy to fill a new RX for Lisinopril 10 mg # 90. I took my coupon from Good RX thinking that I would save money. I did not! When the cashier rang my coupon into the register, the price increased. I ended up paying the higher price as the cashier wouldn't or couldn't void the transaction and start again. I felt really cheated by using the "UN" coupon. Who uses a coupon so they can pay more?? Well, I ended up doing so. I have recommended Good RX to many of my clients as well as patients that visit the physician I work for. I think you should know that this type of thing is happening and I hate for you to have a bad reputation based on this.
