Bring Alexa to college with these awesome back-to-school deals on Echo devices

Now that a new school year is upon us, it's the perfect time to get your dorm room set up with some sweet home tech. To make the decision easier, Amazon has discounted three of its best-selling Echo devices: the Fire TV with 4K Ultra HD is $40 (43 percent off), the 2nd-gen Echo is $85 (15 percent off), and the Fire TV Cube is $90 (25 percent off). You don't need to be a math major to see that those are fantastic prices. The Fire TV stick, Amazon's pendant-style streaming device, is compatible with 4K Ultra HD and High Dynamic Range TV. You'll be able to search through all your apps, from streaming services to social networks, with just your voice via Alexa, built in to the included remote. You can also connect to an existing Echo for hands-free control.
