Kindle Unlimited however seems like its everything for normal E books and Comixology.but I honestly cant tell if Comixology is included in that because Comixology also has a separate subscription (which I assume is more for avid comic book readers only as compared to general readers) but when I click on certain comic books/graphic novels it says included in Kindle Unlimited which makes me think that both are combined in Kindle Unlimited. Go to Your Memberships & Subscriptions and sign into your Amazon account. ComiXology also gives you the option to subscribe to your favorite series, so you never miss the latest issue. From what I read online, it seems like the choices on books and comics are slim as compared to Kindle Unlimited.but with Prime Reading, I also get all of the other stuff with Prime.which can be nice but is unnecessary for me. So it seems to me that Prime Reading is a bit constrained. The problem is, I am a little confused about the different options and such and which one would be best for me. I have a Kindle Fire HD 8th Generation and can finally afford to do a subscription for Amazon. Head Of Product, UX, and Subscriptions at comiXology, an Amazon company.
