Can I participate if my book is enrolled in KDP Select?
The short answer: Yes!
The long answer: If your book is enrolled in KDP Select / Kindle Unlimited, Amazon allows you to purchase a copy of your own book and gift it directly to the contest winners, thus remaining within the scope of Amazon's Terms and Conditions.
Note: For our standard Multi-Author List-Building giveaways and BookBub Follower promotions, you are only required to send a free copy of your advertised book to two winners.
For KDP Select / Kindle Unlimited authors participating in our Author Email Spotlights, please see this related article.
