I have been listening to over the past few months.Yes, it is on Amazon Audiobooks.And, yes once you acquire it on your apps, you can call them and cancel your subscription.

Prior to cancelling you are allowed to acquire additional audiobooks. Anyways, the subscription is monthly and relatively affordable. Courtesy of Jeff Bezos, let's all help him (them) buy the world from us.

My only remark is that the reader seems to not have the ability to pronounce sanskrit words/names. It is a minor issue given the benefits of the convenience that make this available. I don't think it is an autoreader. This human reader didn't bother to try apparently. Again, I use it and am grateful for the technology.
