If the craveskincare.com coupon code isn't working, several steps can be taken. First, ensure that the code has been entered correctly, as it may be case-sensitive or contain special characters. Second, check the terms and conditions of the coupon code. It may have expired, or there may be a minimum purchase requirement. Third, try clearing the cache and cookies on the browser, as this can sometimes cause issues with coupon codes. If all else fails, reaching out to Crave Skincare's customer service may provide further assistance. Remember, each coupon code has its own set of rules and restrictions, so it's important to understand these before attempting to use the code.
