Who needs who more, Amazon or Best Buy?
Amazon understands what all of us do in that people want to test out items before buying them. As a result Amazon signed a deal with Best Buy to be the exclusive retailer for Amazon Fire Smart TVs. For Amazon it will provide them more exposure for people to try out their smart TVs. With Best Buy already selling other Amazon Fire devices, it could mean for more Amazon devices in the home and more customers in the Amazon ecosystem.
Best Buy gains another smart TV to add to their extensive line up. And being the exclusive retailer forces customers wanting to buy the Amazon Fire Smart TV to come to Best Buy. Whether the person buys a Fire smart TV or not Best Buy wins. Majority of the time when a customer goes shopping for a TV they will leave with one regardless if it was the model they were shopping for.
