$25 Discount when you Register by April 25th for the North Pole Santa School
The only costs are for my time. Once I see your files I can give you an estimate of the time required and my fees.
There is no other costs until you order your Proof Copy. For a 200 page book, that should be under $10.00, including shipping.
From then on you only pay for copies you want to personally sell or give away.
