I did a quick scan of this thread and didn't see that anyone had posted this deal yet (my apologies if I missed it).
You can get Kindle Unlimited for three months for 99 cents.

Normally, I would not consider Kindle Unlimited to be worthwhile. It is just too expensive for the selection IMHO.
However, I did want to read Jeremy Robinsons "Jack Sigler (Chess Team)" series, and it is there on KU. So for me, just this series is worth the 99 cents (assuming I can get it all read in the three month window!)
This is apparently not a Prime Day only special ... it runs through the end of this month (July).
There is also a similar promo on "Amazon Music" ... four months for 99 cents. But you have to act quickly to get music promo, it expires today.
