AARP come to our defense to allow us to use discount clubs when we pay cash instead of using Medicare

I have come across a number of programs that could save some of us money by allowing us to use discount clubs when we pay for prescriptions ourselves even though we are on Medicare. I first became aware of this restriction when I joined a dicount club where some prescriptions were cheaper than when I used my private insurance that wanted me to use mail order. Once I became Medicare eligible I could no longer use this discount club even though I was still on my employer's presciption insurance. AARP this is an area where you can save us money. Now that I am on Medicare I pay for all but one of my prescriptions with cash since my medicare and RX prescription benefit does not match what I can pay in cash myself without any benefit from Medicare, but Medicare prevents me from getting an additional discount since I have a membership in the store and would allow me to sign up for their complimentary prescription savings club. This is an area where you can help us seniors save more money.
