I use Good RX every month for several meds including pain medication. My Walmart requires that I have a new, current discount each time I fill. I always text it to myself and then show them my phone. This month I checked pricing and while Walmart and Sam's Club displayed a price, it was grayed out and the price shown was equal to the normal Walmart cash price. Does this mean Walmart and Sam's Club no longer participate in Good RX? Is this only on CII drugs or is it all drugs?
