A. 1. Check eligibility: Ensure that the rewards or coupons you are trying to apply are valid for the items in your cart. 2. Manually enter codes: If the app does not automatically apply a coupon, try entering it manually in the designated field during checkout. 3. Clear app cache: Go to Settings > Apps > Belk > Storage > Clear Cache to remove any temporary data that may be causing issues.

B. 4. Review account settings: Make sure your rewards account is linked properly in the app settings.
