- Check the expiry date of the coupon to ensure it's still valid.
- Verify the code format to make sure it was entered correctly.
- Ensure no sale items are in the basket, as some codes exclude sale items.
- Review the minimum spending requirements to see if the order qualifies.
- Try a different browser or device, as some codes may work in specific browsers.
- Contact customer service to confirm the code's validity and get assistance.
