- Caveat: There's a lot of speculation about Books Butterfly. The current consensus is typically to avoid them.
And another large list of places: http://www.openworldmag.com/dominate-amazon-bestseller-54-resources-kindle-countdown-promo/
- Caveat: Their discussion of Reddit is bad. Don't follow that. Always look at the sidebar rules in every subreddit, read them carefully, and become active before trying to promote.

My Personal List
The promoters in my personal list aren't ranked in any order or anything like that. Bookbub is the best, and the rest are all of decent effectiveness. Also, if you want the absolute best value for your promotions, most of the sites have their own newsletters. Make a new email address, use it to sign up for all the promotional website newsletters, and then get all the promo codes and coupons that the promo sites send to you, saving you money on each and every promotion!
