Diesel US Coupons & Sales

First, go to the Diesel US website or app. Add item(s) to your Diesel US cart, then click on checkout. Look for the promo code, coupon code, or discount code field on the checkout page. Enter the Diesel US promo code into that field, then hit the apply button.

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