The Virtual Bookstore at MBSDirect.net is now open for textbook purchasing. Free Shipping is available for all orders over $99.00 now through Aug. 1. After Aug. 1, all orders over $99.00 qualify for $4.95 flat rate shipping from MBS Direct.

Students will be expected to have the correct student edition of all books on the first day of class.


The first step in ordering textbooks is to obtain the list of courses in which your son is enrolled for next year. Your son’s course list is now visible on MyPriory

An important note: Your courses are visible under the "Progress" tab.  By default, MyPriory will only show your T1 courses.  To ensure that you find all of your courses, you must also click the T2 and T3 tabs to view any courses that do not meet in T1. See the picture below.


The next step for returning students is to determine whether you have retained any books from last year. The list of which books from last year to keep can be found here.

As you select each class, please pay careful attention to any course notifications about the books. Some courses offer eBooks or physical books: you do not need to order both! Some books are marked with “possible previous purchase." You likely have those books from previous years. This is particularly common in the modern and classical language courses.

One of the courses in each grade is called Summer Reading. Please remember your sons need to read these books by the first day of school, so it might be beneficial to order them locally or earlier than your other books so that he has time to read them.


Priory recognizes that the cost of textbooks is a concern for many families and works to hold down costs while keeping our students up-to-date with high-quality, challenging educational material. Through MBS Direct, we offer choices of new and used textbooks and lower-cost digital versions of some books, as well as access to the third-party Marketplace.

The Marketplace option offers cost savings up to 95%, but MBS Direct shipping promotions and customer service guarantee do not apply to those vendors.

If you choose the New or Used offer from MBS Direct (not the Marketplace offer), you will be guaranteed to receive the correct student edition in new or like new condition. In case of questions or problems, you will speak with a live, helpful person at their toll-free customer service center located in mid-Missouri. The 24/7 number is 1.800.325.3252.

Student editions of textbooks are the only editions allowed at Saint Louis Priory School. Specifically, teacher’s editions of texts are not allowed. They are a violation of Saint Louis Priory School’s Honor Code. If you order through the Marketplace or other third-party vendor, check carefully once the order arrives that you have received a student edition. Confirm that the ISBN number on the inside of the book matches what you ordered. Some third-party vendors sell teachers’ editions in place of student editions, often taping over the words “Instructor’s Edition” or “Teacher’s Edition” on the front cover and altering, defacing or covering over the ISBN on the back cover to fool the unsuspecting buyer.


Every year many textbooks with no owners’ names find their way to the Priory lost and found. As soon as you receive this year’s books, please put your son’s name inside the front cover.

If you plan to sell your books back at the end of the school year, do not write on the edges of the books. His name on the inside front cover is sufficient to locate the rightful owner and will not affect your ability to sell back to MBS Direct.

MBS Direct will not buy back books missing covers or pages, with broken spines or with excessive highlighting or margin notes. Stretchy book covers can help protect your investment.
