This is completely normal. Some coupons will have the pharmacy name and price listed, and some will not. You will still be able to use the coupon to receive the price listed on GoodRx, even if it is not displayed on the coupon.
The prices have been negotiated and contracted with the pharmacy. When the pharmacist processes the codes listed on the coupon (Member ID, Bin, Group, and PCN numbers), the current price will automatically be applied in the pharmacies system - regardless of whether the price or pharmacy name are listed on the coupon.
