Replying to myself
Christmas 2023: I ordered a number of books from the local bookstore. One failed to delivered, so
Christmas 2024: I ordered most of my books from Amazon. No two deliveries went the same (see above), total randomness.
Christmas 2025: I ordered ALL my books from the local bookstore (+600$). I started shopping earlier (end of November) and everything went smooth! They kept my individual orders at the shop and I could collect them all in one go. No stress.
The online shop of my local bookstore is simple and efficient. I can read book excerpts, just like on Amazon. But the total absence of clutter makes for a much more efficient experience and a huge amount of time spared.
