It's back to school time and I don't know about anyone else but college was a nightmare sometimes -- trying to find the required textbooks for your classes. It always seemed like I was looking for the best deal out there.

If you need a classic book and are choosing Amazon, beware of the cheap classic books being sold by third-party sellers.

According to WKBW, these third-party sellers can sell cheap, copycat books that you think are the real thing but are really just poor versions of the classics. They are filled with typos and hard to read print.

The problem is they are written in third world countries; copyright protection is just not there.

Amazon says they try to police this the best they can but still, make sure you check the reviews of anyone you buy from so you know you're getting the actual classic books you're paying for.
