Check the fine print for any exclusions or restrictions on the coupon code. Ensure the code hasn't expired and that the terms of the offer are met. Try a different web browser or device as online promo codes can be finicky and may not work in certain browsers. Disable browser extensions temporarily, as they can interfere with promo codes. Clear cookies, cache, and site data in the browser to give it a fresh slate. Try incognito or private browsing mode. If the code still doesn't work, contact customer service for assistance or search for a new working promo code.
