For those Kindle users unfamiliar with buying Kobo ebooks and using on their Kindle ereader this is how to do it:
- download Sony Reader for PC or Adobe Digital Editions (for PC) - because you need to download the Kobo ebook into a PC reader first off
- buy EPUB ebook from Kobo
- download it into your Sony Reader for PC or ADE
- after opening newly downloaded ebook ensure that it's working then open Calibre and import into Calibre where it does it's Alf thing
- then convert EPUB to the Amazon format of choice
- then transfer to your Kindle
Easy peasy
