Most facebook groups only allow self promotion on certain days of the week, if they allow it at all. E-book Authors Promo is a group that is solely for the purpose of self promotion. So, it is there when you publish and it is there when you want to advertise your special rates during promotions.
The group is made up of authors who want to promote their books, and while that would seem to limit your audience, many authors on the site will list the promotions of their fellow authors on their facebook pages.
It is also a place to promote your blog, your author page, and any other pages associated with your printed works.
Here is a link to the page:
