- Check Expiration Date: Ensure the coupon hasn't expired.
 - Verify Code: Double-check for any spelling errors or typos.
 - Read Terms and Conditions: Some coupons have specific restrictions or exclusions.
 - Minimum Purchase Requirement: Ensure the order meets the minimum purchase amount required by the coupon.
 - Product Eligibility: Confirm the items in the cart are eligible for the discount.
 - One-Time Use: Some coupons are single-use and may not be valid if already used.
