I just went and got my textbooks for school. One of them I didn't get because it cost a hundred dollars. Instead I went online and got the previous edition for six dollars, including shipping. If this were a physics or chemistry text I might understand the need for a new edition, but this is an ethics text. The only difference between the two editions is the order the papers are in. I had the same experience with a Calculus text. The worst is that I know there are a ton of people out there who weren't able to return these books and got screwed out of a hundred bucks.
In conclusion, screw you textbook companies.
