For the Kindle users:
Kindle Unlimited is a Subscription Service for Books and Audiobooks
Amazon’s Kindle service is easily the leader in digital book sales, and
a few weeks ago, Amazon took it to the next level. The company has announced Kindle Unlimited, which offers access to hundreds of thousands of books, and thousands of audiobooks for $9.99 a month.
It is not available to you if you have a South African Amazon account but, this never stopped people from enjoying content in any case.
