Bookshop.orgโ โ โ โ โA good place to shop online for books and still support indie bookstores. They sell eBooks too, in standard ePub format.
eBooks.comโ โ โ โ โAn eBook seller with some actual business ethics. No hardware (which simplifies things), but they have an app for Android and iOS, and any DRM-free titles can be downloaded and read on just about anything.
Kobo (eBook store and readers)โ โ โ โ โA solid alternative to Kindle, from the eBook selection through apps and hardware. The app works well on my eink tablet without too much tweaking, though it still wants to sell me more books before I can open the one I want to read.
