Ever wonder how some books garner a double load of reviews in a hurry? Many of them have wised up to the practice of announcing -- and scheduling -- their KDP Free Promo days with more than two dozen websites where you can list your promotion for free. To access a listing of those sites, visit www.justfreeandbargainbooks.com and scroll down to the Author Submissions page. It's totally free and the links help tremendously in boosting the number of your downloads on the days your book is free. Good luck!
