The e-books sell for 25% less than the list price of the printed books and there is no shipping charge. And there is no waiting for it to deliver. You receive a download link automatically upon checkout.
Most of the books are under 2MB and even the larger ones are under 10MB, so downloading is very fast with a broadband connection, pretty fast on an air card and is even still viable on a dial up connection.
