Buying college textbooks is always a big issue for students.  They are so darn expensive, some of mine were over $100.  But you need it, what to do?  So, I had to bite the bullet and shell out my hard earned limited dollars.  

One option is, if you have a friend at copy center, you can make photocopies of the book and return it.  I would not recommend it as it is illegal.  But I have heard people do it.
