Yes, half the pages but setting the printing presses up four separate times rather than once. Also, the costs of shipping are liable to be the same. Like I said costs could be higher or lower.
Edit
Benny's printing presses are in China.

Sorry, I read it wrong.
The books cannot be much more than half ads, that would turn people off from reading them. Leaving less than 16 pages for two stories per book, would not give readers much story to get acquainted with the characters.
And, I agree the FCBD books are a way for REDG to get both retailers and readers interested in REDG's products, not just free books.
