Including 500 to 1000 word articles. I would like to write about 2 per week available to the public for FREE. Then later in the year, publish a book for which there would be a charge. Also can the charge for books be as low as $4.99? Five bucks seems to be what a lot of folks will pay without thinking too much about it. $9.99 might be too high.
When reading up on the subject for my own nefarious purposes, the optimal price point for self-publishers seems to be $2.99 — any lower and you don’t get enough additional sales to cover lower margins, and and higher and you lose too many sales.
