Fall Textbook Purchasing and Buy-Back is Coming Soon!
Textbook Buy-Back Options
Online: Now - see what books MBS will buy back from you
Book Drop-Off Day
All Grades 6-12: Fri., June 3, 9 a.m.-2 p.m.
For your convenience there will be two drop-off locations: middle school and upper school receiving areas.
Please, park your car and walk your books to the receiving area. Have your MBS Direct quote with you.


Below you’ll find all the instructions you need for purchasing books and participating in the buy-back.

Buy-Back How-To
Step 1: Visit the MBS Direct website by going to the main Harker Parent Portal page and clicking on the blue tile called “Bookstore.” Once on the MBS page, click “menu” and then click “Sell Your Textbooks” and log in to your MBS account. (If you do not have an MBS account because you’ve never purchased from them, you can create an account at this point.) Enter your all your books’ ISBN numbers in the big blue box, click on “Price Your Books” and you will be told whether your books are available for buy-back. You may enter the ISBN numbers of any books, even ones you did not purchase from MBS. You will then receive a quote that guarantees your buy-back price for any approved books. You MUST bring a copy of this quote with you when you drop off the books.

Step 2: You can either send your approval certificate and book(s) back to MBS directly (a UPS label will be provided by MBS), or bring them to our Buy-Back Drop-Off Day, where Harker will collect your textbooks and send them to MBS (see next paragraph for more on that). However you choose to return your books, you will either receive a check from MBS, or you may have your amount credited via PayPal, which can take up to four weeks. Please remember that this day is set up as a convenience for Harker families to drop off textbooks that MBS has agreed to purchase back from you.

MBS Direct Rental Textbook Returns
Rentals are not to be dropped off with the books that you are selling back to MBS Direct. Rentals need to be sent back directly to MBS as it is a different location than where buy-backs are processed. Please look for an email from MBS Direct as to where to send your rental books back. MBS Direct will provide a shipping label to send the books back.
Buy Fall Textbooks - Beginning Fri., July 8
MBS operates an online bookstore for Harker. The link to this online bookstore will be on the Back-to-School Hub, which opens June 8. Starting July 8, you can input your student’s Harker ID at this virtual bookstore and all the books you need for your student’s classes will appear. We realize some of you may purchase books by other means, so it is important to make sure that when buying a book, the ISBN number exactly matches the one on your book list – even numbers different by one digit will mean the incorrect book.

Textbook orders of more than $99 purchased between July 8-14 will receive free shipping from MBS.

We have prepared a short simulation tutorial to walk you through the book-buying process with MBS. A hard copy cheat sheet is also available.
If you have any questions about MBS buy-back or book purchasing, please contact me at bookstore@harker.org or 408.553.0356.

Have a great summer!
