As of 2006, Mercersburg has contracted with MBS Direct to provide textbooks for all courses. Textbooks will no longer be sold in the school store.

Students may order their books online or by phone or mail. Books can be ordered approximately three to four weeks before school starts and can be sent to a student’s home or to Mercersburg, for pickup after the student arrives. All orders are processed within 24 hours of receipt, excluding weekends. Books are returnable and also may be sold back to MBS at the end of the year. Students receive detailed information about this program during the summer.
