GoodRx‘s cash prices are based on multiple sources, including published price lists, purchases, claims records, and data provided by pharmacies. Our discount and coupon prices are based on contracts between a pharmacy (or pharmacy purchasing group) and a Pharmacy Benefit Manager (PBM), who provides prices to us. The prices we show are our best estimate; while we believe our data to be generally accurate, we cannot guarantee that the price we display will exactly match the price you receive at the pharmacy. For an exact price, please contact the pharmacy. (Please keep in mind that the pharmacy will require the information shown on the GoodRx coupon/discount to confirm the discount price.)
