Might be a PM, not sure. I think it has to be an error, Comes with Kindle Unlimited with auto renewal but you can cancel as soon as you get it.

Picked up 2 right away (after already buying a refurb for $ 79 🙁 )

Edit, I looked at my Kindle Unlimited membership and, with the two I bought today (that comes with 3 month unlimited) with the free 3 month trial I’m already on, it all just extended my membership. Says I will not be charged until Nov-30-21! Nice stacking!
