However, executives declined to specify by what extent the average shipment has grown. Amazon said its operating profit, which does not include charges for interest, stock options or one-time expenses, totaled $1.7 million. Amazon also said it will lower prices by 30 percent on books over $15. The price cut is an extension of a discount program Amazon started last July offering 30 percent off books over $20. For the current quarter, which ends July 31, Amazon said it expects to post revenue of between $765 million and $815 million. For the full year, Amazon said it expects net sales to grow by over 15 percent compared to 2001.
