On the Internet, doing business involves a lot of transparency. Traditionally, before the age of the Internet, if you ever want to buy a textbook, you will have to visit a brick and mortar bookstore. Once there, you search for the book that you are looking for, and if you find it, you will most likely buy it there and then. That's because you are already physically in the bookstore. Traveling to another bookstore just to compare prices just isn't a practical thing to do.
