Financing Terms: Regular installment apps like Klarna or Afterpay are not supported. You can link your HSA or FSA cards directly to pay for medical items. App Quirks: The website takes standard credit lines and PayPal, but it blocks Apple Pay. You must use the official CVS app if you want to store digital payment shortcuts. In-Store Payments: Registers and pharmacy counters accept Apple Pay, Google Pay, and Venmo QR codes. Tapping your phone automatically applies your linked ExtraCare rewards at the counter.
