The Amazon Fire TV Stick 4K is sale for $39.99. This price is only $5 more than the lowest price that Amazon has ever sold it. The Fire TV Stick 4K is the most powerful streaming device Amazon currently sells. Even if you don’t have a 4K TV, it is highly recommended to pay the extra $10 to get this model instead of the regular Fire TV Stick, which is currently on sale for $29.99. That’s because the extra power will keep the device running smoother for the long haul and it has better WiFi connectivity, among many other improvements. It comes with the new Alexa voice remote with power and volume buttons built-in, as do all current Fire TV models. Also on sale is the Fire TV Cube for $79.99 and the Fire TV Recast for $189.99.
