Prices increase as the year continues on, so it is important to purchase your book as soon as possible. Prices begin at $70, and will raise to $90 throughout the course of the year. After the books have been delivered to the school, there will be a limited quantity to purchase on campus for the $90 price, and there is no guarantee that students will be able to purchase one at this time. MIHS Staff members may purchase a book for $60 by bringing their money to Kayla Canada.
