Promo codes can be entered at Checkout after the “Cart” and “Login/Continue as Guest” pages.
In order for the code to go through, both the shipping and billing addresses must be filled in on the “Customer Information” page.
When successful, you will see an update on the top of the next page that the price of your book(s) has changed.
This page will also reflect if there is free shipping.
Mobile checkout should be the same but skinnier.
Any issues with a promo code should be referred first to HFS at [email protected] or call 1-800-537-5487 before submitting your order. Their representatives are available to assist you Monday – Friday, 8:30 AM – 5:00 PM Eastern.
