Sundeep has a friend who has created a Christmas book for children and he wants to help them maintain inventory for selling their book online. Leo says that self publishing is a great way to go, but doing your own fulfillment is not. He should check out the book "Author Publisher Entrepreneur" (APE) by Guy Kawasaki. Printing on demand is a great way to go. They should check out Lulu.com for this, and they can even sell through Amazon. Leo also recommends shipping via Stamps.com. That way, they can print postage directly from the computer and can even integrate through the USPS via media mail.
Check out the book No Chimney, No Problem. It's a great book about how Santa gets in when you don't have a chimney!
