<p>A book form with any type of binding and format can be enhanced by including pages of advertising with integral vouchers for products and services. The publisher can receive some revenue from the advertisers for every voucher that is submitted by customers, thus reducing the cost of publishing and being able to pass on cost saving to make the selling price of the book more attractive. The vouchers can be printed on the same paper as the book and/or the advertising pages, or they can be highlighted by different colours and texture.</p> |
