I have used GoodRx at Walmart, Tom Thumb and Albertson's Stores with excellent savings. I have found that you MUST ask the Pharmacist to let you know if the cash price is cheaper than if you use your insurance plan. They may not be able to let you know of a lower price, if you do not ask. I have found on multiple occasions the CASH price (with a coupon) is less than my copay. As noted below, some people have called first and confirmed the Pharmacy accepts GoodRx, with good results.
