Walmart will accept the coupon, but will not always honor the price. According to the person I talked with at GoodRx Customer Service, GoodRx no longer has a contract with Walmart so they do not have to honor the price. It is at the discretion of the pharmacist. My recent experience, they accepted the coupon, but did not honor the price. When I checked my email, Walmart had sent me a different discount card that would have offered a significantly lower price.
