For the last several years I've had terrible luck with number 3, though I supect that's entirely amazon's fault rather than calibre. It's a real shame too because I used to buy a lot of books, but once I couldn't read them on the device I wanted (like Remarkable tablet) there's no point in buying anymore so I stopped. I still buy from DRM-free sellers, but most of the books I want to read are only available through the popular e-reader store.
