Kewusuma's discount codes are only applicable to full-priced and in-stock products for the active duration of the code. This means that if there are any products in your cart that are already discounted, pre-ordered, or back-ordered your discount code will not be applicable to those items. All of our discount codes that are shared via email or social media only last for a limited amount of time, so be sure to double-check if the code is still active.
