Marketing and advertising books via various internet sites is becoming most popular with traders. This is chiefly because it costs less to publicise the actual book, as compared to traditional methods such as conferences and advertisements on billboards and in newspapers. Books are also stored in large warehouses prior to being dispatched to customers, nationally and internationally. Therefore overheads are also less. Whilst this may be true, publishers feel that they are not gaining an adequate amount from book sales, and are not just demanding that they are paid for the cover prices of the books, but also that they receive a percentage of the actual amount received for them. However, these discounts only seem possible on books which are bestsellers.
