Add Audible book to your purchase for just $1.99

When is your audiobook available as an add-on purchase to the Kindle version?

And when it is only available from Audible?

It’s the same company, why is it sometimes available as simpler additional purchase and when not?

For me, it’s also a question of convenience. I prefer to listen to my audiobooks using Whispersync for Voice. This means you can use your Kindle app (on your phone) and switch back and forth.

Frankly, this is a big difference from using your Kindle app to read and your Audible app to listen.

So why is one the one way and the other the other way?

Dunno.

But this one is $9.95. Why?
