The deal is available for both new and returning subscribers who are also Prime members.

You'll have until the Prime Big Deal Days event wraps up on Oct.

8 to sign up for free.

I sign up for this deal whenever I'm eligible (generally a few times per year during Prime events), which means I have to cancel every so often.

But Kindle Unlimited is one of the only subscriptions I do actually pay for throughout the rest of the year.

I cannot recommend it enough for anyone looking to up their reading numbers.
