Currently, there are no specific coupons available for Lipitor at Walmart according to the Walmart website [3]. However, it is advisable to check with the Walmart pharmacy directly or use platforms like GoodRx to find potential discounts on Atorvastatin, the generic version of Lipitor [2]. DrugPatentWatch provides information on the patent status of Lipitor, which can be useful for understanding when generic versions may become available [1].
