I feel like I'm one of the few people that still does purchase books. In 2020 & 2021 I bought music theory books from amazon + jazzbooks.com, and I had some Korean books imported by a friend. I have the space and bookshelves to house them though.
Yeah, there were multiple books that I read the reviews on amazon and people were complaining about the poor print quality. One of the Ted Greene books I got had a typo on the 2nd page in the table of contents, so I'm not sure if any proof reading is being done really.
I’m on 20+ books read in my good reads challenge for 2021, all paid for, many through audible but some directly from the black library (yes it’s very stupid warhammer fiction), but all of them have been audiobooks and the ones I didn’t get through audible cost me 33 euros a piece. So you’re not the only one buying books, there is at least two of us!
