Kobo Books vs Books on Google Play

For some reason not all the eBooks available on the Kobo eBook site are downloadable as .ascm files. Most likely Kobo leaves this up to the publisher, as Houghton Mifflin Harcourt does not have a single book on the Kobo store that offers a separate .ascm download. What most users are unaware of is that the Kobo store is not primarily an .epub bookstore. Kobo uses a proprietary format called .kepub that only works on their own Kobo branded devices. Many of the books they sell do offer a separate .ascm file download, but not all. What exacerbates this issue is that there is currently no way for a user to know if an .ascm will be offered until after purchase.

Depending on whether a user is logged in, different prices will be shown on non agency eBooks. Non agency eBooks allow for Kobo to set the price of the title instead of the publisher and sadly it does appear as though Kobo has taken advantage of this to entice new users into thinking their books are priced lower than they actually are.

Upon close inspection Books on Google Play does not actually follow the normal standards when displaying user uploaded .epubs but rather has it's own secret method of how it handles the internal .css and HTML. This can result in display problems for user uploaded content.
