Discount codes don't stack. If you have 50% off discount, they can't also use a "free shipping" coupon since Only one discount at a time can apply to a single order at the Enginediy site.

Of course not, most coupons may be used only by you when you received them directly from Enginediy. As the Enginediy coupon includes your User ID, it cannot be resold or transferred in any way.

Most Big Discount Events of the year witnessed a vast number of coupons from Enginediy released. Especially, on federal holidays such as New Year’s Sale, Thanksgiving, Christmas... or on other important days such as Valentine’s Day, Easter, and Father’s Day..., customers also can buy at Enginediy with numerous coupons.

Yes. Coupons for each Discount Event of Enginediy will be collected here while being updated day by day. Sometimes, there will be deals not updated promptly but it's rare, we expect sympathy from you. 

At the time of updating, Enginediy has not applied Student Discount all year round yet. Check the official store and reach out to the customer support team to be clear.
