But with respect to the agency discount, Amazon demands that all non-Big-Six
trade publishers sell it their
ebook and physical book wares under the old
trade discount model, which requires only that Amazon buy inventory at roughly 50 % off the publisher's suggested list price (the discounts
vary by publisher and can run as high as 55 %) and is silent on pricing — allowing Amazon to discount as steeply as it wishes to win over customers.
