There are several potential scenarios where a Diono promo code may not work:

1. It might not be valid without reaching a minimum dollar amount.
2. It might not be valid for specific items in your Diono shopping cart.
3. It might only be valid for first-time Diono customers.
4. It might be past its expiration date.*

If a Diono code doesn’t work at checkout, try another one if more are listed. Alternatively, try these promo code hacks to see if one works. You can also try abandoning your cart (while you’re logged in) to see if Diono sends you an email with a coupon code as an incentive to complete your order.
