Bargain Book Websites - How many copies do you really sell?

Bargain Book Websites - a blog post

I've written a blog post about Bargain Book website and how many copies of The Archivist I sold during a five-day $0.99 promotion.

I looked at:
*Bargain Booksy
*Book Barbarian
*The Fussy Librarian
*Booksends

Possibly of interest to those who write as opposed to just read.
