Wish has specific policies regarding the use of coupons or promotions that can vary based on the individual offer and the items in question. Generally, users can apply one coupon or promotion code per order. This means that if you have multiple codes, you will need to choose the one that provides the best discount or benefit for your purchase. It is also important to note that some promotions may only apply to specific products or categories, so reviewing the terms and conditions associated with the discounts is advisable. For the most current information regarding coupons and promotions, it may be helpful to refer to the relevant sections of the Wish website, where you can also find any updates on promotional policies.
