How do I redeem a Diono promo code?
First, go to the Diono website or app. Add item(s) to your Diono cart, then click on checkout. Look for the promo code, coupon code, or discount code field on the checkout page. Enter the Diono promo code into that field, then hit the apply button and check your savings.
Example:
Why didn’t my Diono promo code work?
There are several potential cases where a promo code may not work at Diono:
- It might not be valid without reaching a minimum spend amount.
- It might not be valid on specific items in your Diono shopping cart.
- It might only be valid for first-time Diono customers.
- It might be past its expiration date.*
If a Diono promo code doesn’t work at checkout, try another one if more are listed. Alternatively, you can try these promo code hacks to see if one of them works. You can also try abandoning your cart (while logged in) to see if Diono sends you an email with a coupon code as an incentive to complete your order.
