Textbooks are expensive

I went to the bookstore at school and got my textbooks since I can charge there with my financial aid now. My statistics instructor changed the book so I couldn't use the one I already have, and the one at the bookstore was $121. Are they kidding? I'm never going to the bookstore to get my books again. I had to borrow more money but I also found my textbooks online and am getting them both for $145. Hopefully they are functional for my class! You never know with online purchases... But there was no way I was going to pay that much for the one book. Now I have found the economics book for less as well and I have these older editions of economics books I bought for $70 from a friend and I need to get rid of them somehow. They are outdated, one says 05/06 on the side of it. Who would want that? I should just get over it and recycle them. I don't know what I was thinking when I bought them... I was obviously still naive to the textbook scam. Of course they're going to change editions before you get a chance to take the class! Duh. I'm gonna end this Carrie Bradshaw style with a question - why is everything made so hard and expensive for all the people who have very little money, like students?
