<p>Anyone remember that story about 2 books listed on Amazon that went up to $130 million or something ridiculous, because they both priced their books in terms of the price of others and went through this loop where the price increased every day?</p>
<p>I never found textbook prices to be a problem. If it was an actual textbook it was available in the library when I needed it. 80% of the time you could download the PDF for free too. </p>
