That depends on what book you read ~ If it's a best seller, it's about 40% off from the publisher to the book wholesaler, and about 70% off from the book retailer. If you buy it now, it will be full price!

There is also a special price book, which is not very popular ~ published by a heavy publishing house, with a maximum discount of 10%. It's about 20% off at the book wholesaler and 40% off at the retailer. You can buy it at half price!
