The first blog post in the series (link below), was very effective for all the people who used it and continue to use it.
But there are a couple scenarios in which the first textbook tactic is not possible, one of which will be discussed in this blog post.
Imagine a professor that is so heartless toward her student's wallets, that she decides to compile 4 various textbooks into "her own" compilation textbook. That's the book seen in the image above.
That book costs $157. That's right. A thin, cheaply made, paper back book that a teacher quickly threw together costs $157.
Guess what? I bought it. I had to... or so I thought.
