The bad news is that although I always sold for less, I can no longer maintain a direct outlet for books and study aids. However, I can link you to the publishers directly, where you can take advantage of free shipping and special coupon offers. I make no commission in doing so. By ordering directly you will promote competition and send a message to bookstores that try to sell at inflated prices. Students have told me that they endorse this endeavor.
All power tends into a government in itself.
Power that controls the economy should be in the hands of elected representatives of the people, not in the hands of an industrial oligarchy. Industrial power should be decentralized.
