E-book publishers are trying to entice readers with daily deals, but the long-term consequences of the low prices may be troubling

Companies such as BookBub.com and BookGorilla.com are offering readers e-books for as little as 99 cents, powering sales for publishing companies but also raising concerns about the long-term effects of the extremely low prices. The goal of the low prices is that readers will get hooked on a series or author and eventually pay for full-price books, but readers may get used to only paying low prices and only purchase e-books when they’re on sale. Kensington Publishing Corp. runs promotions through BookBub that it says have all been successful. Its chief executive Steven Zacharius says: “We know we might be shooting ourselves in the foot. But I can’t resist because it’s such a good way to stimulate sales.”
