Discount codes don't stack. If you have 53% 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 Samsung site.

To avoid this problem, you should check out carefully Samsung 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.

Yes. Coupons for each Discount Event of Samsung 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. 

Shoppers can get coupons for their first purchase at the store. However, it is not all the time, sometimes, they cannot apply a discount on items selling out or items not contained in the promotion program. It depends on the time you shop at Samsung.

The sitewide discount from Samsung is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.
