If a Domino's coupon code isn't working, consider the following steps:
- Check for typos: Ensure the code is entered correctly without any mistakes.
- Verify expiration date: The code may have expired.
- Usage limit: The code might have already been used or reached its usage limit.
- Promotion restrictions: Some codes are only valid for specific items or locations.
- Contact customer support: Reach out to Domino's customer service for assistance.
If none of these solutions work, the code might be invalid or no longer available.
