Agreed. Bubble envelopes can work okay if they are the correct size, but I often get normal-sized books shipped to me in XXXL size Amazon envelopes. These mailer envelopes are big enough for the book to rotate freely in amy direction inside of the packaging. So it’s inevitable that it arrives with creased or torn pages and jacket. I even had one where the cover separated from the pages. Horrible. My preferred approach now is to use niche-retailers for things I care about arriving intact on the assumption that if your entire business is about that product category then you should be knowledgeable about how to ship those items safely. Barnes & Noble for books, B&H for camera, BestBuy for consumer electronics and video games, etc.
