Amazon has just put the Fire TV Stick 4K on sale for $39.99. This price is only $5 more than the lowest price that Amazon has ever sold the 4K Firestick. This newest member of Amazon’s Fire TV lineup is the most powerful streaming device they currently sell. It comes with the new Alexa voice remote with power and volume buttons built-in. Amazon has said that it has already outsold all previous 4K Fire TV models before it and its 4.4 star review rating shows that they’ve hit a perfect sweet spot between functionality and affordability. Also on sale is the Fire TV Cube for $79.99 and the Fire TV Recast for $189.99.
