Discount codes don't stack. If you have 55% 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 se-ed site.

To avoid this problem, you should check out carefully se-ed promo code before that promo code could be expired, some promo codes are tied to a minimum purchase, a first-time purchase, or tied to geography, and other reasons.

In case you need to change another se-ed Coupon Code, or you no longer want to use the item, you can cancel your Coupon Code by a press on the Cancel tool at se-ed. We will support you if you have any trouble via our mail.

Usually, Coupon Stacking is not allowed at se-ed. However, the store will surely give out notice if available.

There is no certain number for the frequency of releasing coupons from se-ed. But, most of the time, there will be at least one available. Special Discount Days such as Black Friday, Cyber Monday, Back to School Sale... come with many coupons.
