Below is a list of more than 70 Facebook groups that allow authors to share their free giveaways, discounts or Kindle Countdown deals, or to let members know they can read books in Kindle Unlimited. The column on the right shows what is permitted, but please make sure you join the group and read ALL terms and conditions of being a member and promoting there. If you would like your Facebook group added to the list, please leave a comment below with the link and what you permit, and I’ll get add it. Feel free to share any I might have missed in the comments too, and good luck with your promotions! Besides being a member and utilising these great groups, I have no other affiliation or financial interest in any of them!
