I see that you can get 3 months of Amazon Kindle Unlimited free as a part of prime day (maybe only for Prime members, not sure but I am a member). This is great timing for our trip.
My question is--do I need to download on the device I would be using it on only? Can it work on 2-3 devices either at different or the same times (mine and my kids)? Oh, or do I just download books and then can use as wanted? If that is the case, can I do this on more than one device?
Thanks!
