Is buying a book this way cheaper? - Paperight/website GitHub Wiki
Most of the time, buying a book, or licensing a copy, from this website will be between 10% and 30% cheaper than buying it from a traditional book store. The total price of the book is made up of the license fee, plus what you decide to charge for printing and binding. Much of the cost will depend on what you as an outlet decide to charge for the printing of a double-sided A4 black and white sheet of paper.
The lower you are able to make this charge, the lower the total cost will be to the customer, and the more likely your customer will be to choose to buy books from you, rather than a traditional bookstore.
