- Where can I find a valid DIFF Eyewear coupon code?
The best place for a current DIFF coupon is our official website's promotion page. You can also sign up for our email newsletter to receive exclusive promo codes and special offers directly in your inbox, ensuring you never miss a sale or discount.

- What is DIFF's free shipping policy?
DIFF Eyewear offers free standard shipping on all orders over $50 within the contiguous U.S. If your cart doesn't meet the threshold, a flat shipping rate applies. Keep an eye out for occasional site-wide free shipping special offers announced via our marketing channels.
- Why is my DIFF coupon code not working?
Your code may be invalid due to several reasons: it has expired, doesn't apply to the items in your cart (e.g., sale items), has minimum spend requirements, or was entered incorrectly. Double-check the code's terms and ensure no spaces are copied. Contact support for further help.
- Can I use multiple promo codes on a single DIFF order?
No, our system only allows one active promo code per order. You cannot combine multiple discount codes. However, certain automatic promotions (like free shipping on orders over $50) may sometimes stack with your single, applied coupon code for maximum savings.
- Does DIFF have a first-time customer discount?
Yes! We love welcoming new customers. The best way to get a first-order discount is to subscribe to our email list. New subscribers often receive a welcome promo code for a percentage off their first purchase, giving you an instant discount on stylish DIFF eyewear.

- Are DIFF promo codes valid on all products, including new arrivals?
Most promo codes are valid on our entire collection, but some exclusions may apply. Certain special offers or codes are specific to sale items or may exclude new arrivals and collaborations. Always check the specific terms and conditions of your coupon code before applying it.
