Printing books is so expensive and you can use the book calculator on selfpublishing.com to see. You would have to print about 1,000 books or more to get a good rate but are limited to one book. Then you have to pay the printer fee of about $100 for each book for formatting and sending you a proof. Then there's the shipping which comes out to be around $3 (give or take 18 cents) for media mail per book.
