I stopped using Amazon a while back, but it was where I got all my books for a long time. I do thriftbooks mostly now, and try to buy directly from publishers when it’s a newer book, but I’m always interested in finding new spots to cop some sweet books.
Honestly, I couldn’t figure out how to do it with Calibre. I still use that for keeping my stuff organized tho. Calibre is legit, especially if you get into data hording territory.
