Romance Day · Nov 6, 2026

“It far surpassed my expectations. I had 407 downloads, which shocked me. So excited to have my book in the hands of that many potential readers. Even if only a small percent actually read it, that's a significant number of new readers. I already see a bit of a difference in my Goodreads shelves as well (reading and want-to-read). Thanks for helping authors coordinate this!”

Author FAQs

Do I need to make my book free on Amazon during the event?

Yes. Your book must be free on Amazon Kindle during the event live dates. If it is not free then, it will not be added to the event.

What is the Top Placement add-on?

Top Placement ($3.00) puts your book at the top of the Stuff Your Kindle Day page, so it is one of the first titles readers see. It is first come, first serve based on when submissions are received.

What information do I need to submit my book?

You will need your author name and email, ASIN, title, regular price, page count, publication date, Kindle Unlimited status, genre, description, and a book cover image. You must also confirm that the book will be free on Amazon during the event dates.

When will I know if my book has been accepted?

Books are checked on the event start date. If the book is free on Amazon then, it is accepted and you are notified by email.

Why does PayPal show BookBelow?

BookBelow is our parent company. You will see that name during PayPal checkout and on your transaction details. Your StuffYourKindle submission is still processed as usual.

Do I need an account before I submit?

No. Fill in your author name and email on this form. After a successful submission we create an account if needed, sign you in, and email a login button (plus a temporary password if you are new).
