Amazon's Alexa push is making customers buy more

Amazon announced its earnings for the third quarter of 2017 on Thursday and to nobody's surprise, the internet shopping titan revealed that it has sold a whole bunch of products for unfathomable amounts of money. The company reports that it sold $43.7 billion worth of merchandise in Q3, that's a 34 percent increase over the same period last year. However, if you don't count the $1.3 billion in sales that Whole Foods earned during that time, the company's net sales only increased by a measly 29 percent year-over-year. So where did all this cash come from? Well the Whole Foods acquisition in late August definitely helped, but Amazon also introduced three new Echos (the second-gen Echo, the Echo Plus home hub, and the lightweight Echo Spot) as well as new Fire TV, which supports 4K and integrates with an Echo for voice control.
