You are about to leave www.bjupresshomeschool.com (homeschool content) and go to www.bjupress.com (Christian school content and supplemental Textbook Resources). These are separate sites, so your login session and shopping cart will not transfer between them. (However, both use your same BJU Press account, so you only need to register once, and any change to your account or order history will appear on both sites.)
Your account is the same.
Your cart is not transferred.
