Why Must Read Bryan A. Garner's Redbook: A Manual on Legal Style, 4th Edition (Coursebook)?

The content of this manual is not the issue. It's the deplorable fact that we are being charged almost $60.00, for the poor-quality paper that the pages are printed on that rip easily, and a cover that is just as cheap. The author and publisher should be ashamed of themselves putting a product out like this. Boo on them.
