A. Before completing your purchase, double-check that the discount code is entered correctly in the designated field during checkout. Ensure there are no extra spaces or typos. If the discount still does not apply, try refreshing the page or clearing your browser's cache and cookies, then attempt the checkout process again.
B. If the discount was supposed to be applied automatically, verify that the promotion is still valid and applicable to the items in your cart. If the issue persists, take a screenshot of your cart and the promotion details, then reach out to customer support via email or chat for assistance.
