I'll make this brief and right to the point. Some books can be purchased only at the University bookstore. Those ones you just have to buy. To buy some of the required books, that are available elsewhere, from the University bookstore would cost me $261.84. To buy the same books from Chapters Bookstore will cost $183.27. That is a savings of $78.57. Wow.

Update on Book Buying Strategies:
The thing about ordering my books online is that I'll have to wait for them to arrive. Now what I plan to do is buy the books that I absolutely need from the bookstore and return them before the end of the 15 day grace period. That is all.
