I use goodrx at Walmart I checke every month to make sure it's still the same price or cheapest price. I have no insurance. I take 12 different medications. 5 are suppose to be paid by workers comp. If for some reason the prescription comes up different price, I show coupon and they run it back through. I've tried Walgreens once because it showed 1 of my expensive was cheaper there, they said they would have to run txt through so transferred it to Walgreens showed coupon and said they wouldn't accept it. So I transferred back to Walmart. I recently found cvs actually has 2 my RX's which I used coupons and they actually came out to be lower price than coupon as cash pay with no insurance. I don't know how I could afford all my medications without this app.
