I did not planned originally, but I will release hardcovers first.
Hardcover $29.95
Paperback $19.95
1. Some people buy hard covers only.
Just like I buy paperbacks only.
I do not want to lose those customers.
2. Hard covers make paperback look cheaper.
There are people wasting time on being jealous while others spending time on making more money.
That is why I can make money without going to work.
