The FCBD books are 32 pages each (not 60+)
there are four different books each containing two stories
REDG is printing 100,000 books each and bundling them charging 5 cents to retailers (through Diamond) per bundle of four books.
Revenue through Diamond 100,000 bundles (of four books) times 5 cents equals $5,000.
Assuming half the pages are dedicated to ads, 16 pages per book, That leaves each story with an average of 8 pages.
Again, assuming the costs are similar for the FCBD books and the Giant Size free books (60+ pages), REDG estimated costs (printing and shipping) was $0.53 per book. The cost could be too high or too low.
Estimated cost of the FCBD books is 400,000 times $0.53 about $212,000
REDG said they were shooting for a CPM rate of $33.
Estimated ad revenue 33 times 400 times 16 equals $211,200. you can add in the $5,000 from Diamond, it gets you to $216,200
