Fire TV Stick Lite | $20 | Amazon
Why replace your old TV when you can just make it smart with a little black rectangle? Plug the Amazon Fire TV Stick Lite into the back of your TV and use the included Alexa Voice Remote Lite to boss it around. Watch any of the best streaming services of the day using this little HD streaming stick, including over 200,000 free movies and shows on ad-supported services like IMDb TV or Pluto TV—the latter of which has a whole channel that exclusively shows MST3K episodes 24/7, perfect for my fellow old nerds. Because of its slight form factor, you don’t have to worry about it taking up space or even being visible at all. The easy-to-use remote comes with a built-in microphone so you can search for your favorite shows by simply holding down the microphone button. At just $20 in this sale, it’s the cheapest way to make your dumb TV smart.
