We can help you troubleshoot this one! First, check that you’ve entered the code correctly. (Sometimes O's and 0's can look similar.) If the code is correct, then check that it hasn’t expired, and that you qualify to use the code. The error message you see when applying the code should tell you if either of those issues are preventing it from applying to your order. If the code is entered correctly, it’s not expired, and you qualify for the promotion, but the code still isn’t working, chat with our Member Services team and they’ll be able to assist.
