By signing up for DEI email newsletters you will receive discounts and promo codes sent directly from DEI as soon as they are available. These include offers exclusively for subscribers that you won't want to miss.
Follow DEI on Facebook, Twitter and Instagram. Occasionally DEI will post new coupons and offers to their social pages.
Sometimes simply asking customer support for a DEI promo code will score you a great deal. Connect to live chat or send an email explaining how much you love DEI and you just might get a special discount.
Proceed to DEI and add items to your shopping cart. Just before completing your purchase, leave. If DEI's marketing team is on point, they will reach out asking you to complete your order. Often DEI will include a promo code to convince you to finish the purchase.
Coupon extensions like Honey will test codes for you on the fly when checking out at designengineering.com. These apps aren't always perfect, but when they work they can save you time and money.
There are many reasons a promo code may not work. Some of these include product exclusions, order limits, price thresholds, and other restrictions. Make sure you test all promo codes first before completing a purchase. If your cart is not discounted immediately after entering a promo code, it likely does not work.
Occasionally DEI will extend a promotion or reuse a code at a later date. If there are no active codes, try out some older ones -- they just might work!
Of course! Fill out our contact form with the subject line "DEI Promo Code" and include all offer details. Once verified the code will be added to this page.
