An Unexpected Price War Is Making Amazon Book Prices Lower Than Ever

Amazon appears to have slashed the prices of its books, thanks to an Overstock.com promo in which it priced all of its books at least 10 percent below Amazon.

The aggressive pricing strategy has been enough to see Bezos & Co. cut the prices of hardcover book by between 50 percent and 65 percent compared to the usual cover price. Those kinds of discounts have never been seen on Amazon before; typically, it knocks around 40 to 50 percent off as a maximum.
