You can rent them for a whole semester for extremely cheap prices and at the end of the semester you ship them back to Chegg for free. Unless you HAVE to buy the book or think you're going to use it in the near future, just rent them.
Most of the time Chegg is cheaper than Amazon but not always, so make sure you compare prices first.
I don't usually have to own them, i'll have to check this site out next semester thanks!
