I saw a $75 textbook on Amazon that I wanted. But every book I've bought from Amazon has been so badly made that I consider this a last resort. While wondering what to do, I came across this. "First a rant: What has happened to the once high art of bookbinding? I have hardcover books, with sewn-in signatures, that have stood up well to decades of extensive use. Some softcover books, particularly the older ones from Dover Publications, have also stood up well. But virtually the entire publishing industry seems to have given up on the idea of making well-constructed books for reasonable prices. "Clifford Algebra to Geometric Calculus", with its poorly glued spine and paper cover, is my outstanding example of the _worst_ of this trend. Even though I handle my books with reasonable care, my not-inexpensive softcover of "Clifford Algebra to Geometric Calculus" started to fall apart almost immediately, before I even made it halfway through Chapter 1. I would have purchased the hardcover version with a "library binding", but the extra expense (more than $150) was so extravagant as to be beyond my means." -- Gregory Grunberg. Did he really mean that a hardcover cost $150 more? Or $150 total? I checked out used book on eBay but they cost significantly more than new.
