Cost of sales at Amazon leapt about 33 percent, eating into net income, according to the earnings report. Amazon has been pushing to deliver packages more quickly, promising a wide selection of items to arrive within a day of being ordered by members of its Prime subscription service. "We are ramping up to make our 25th holiday season the best ever for Prime customers - with millions of products available for free one-day delivery," said Amazon chief executive Jeff Bezos in the earnings release.
