Have you heard about this new offering from Amazon. I have to agree with Mark here and just like KDP Select limits Indies options, so does this program. I like that KDP Select lets you opt out after a certain amount of time. I used it for one of my ebooks and opted out when I allowed to by the program. I think most authors do this. I don’t want to sell my book exclusively to anyone.
I have not gone into the details of this subscription service, but since it requires you to be in KDP Select to be a part of it, I’d read the fine print before I jumped into that boat as an author. As a reader, I don’t read on my nook enough to subscribe to any ebook subscription service, but that’s just me.
