The all-new 3rd-generation Amazon Echo Dot has just gone on sale for $39.99, which is 20% off of its regular retail price. This is actually only the second time the new Echo Dot has ever been on sale, with the first sale being the multi-month long holiday deal that lasted from Thanksgiving through January. For an extra $10, you can get the Echo Dot + Amazon Smart Plug bundle for $49.99. The Amazon Smart Plug normally costs $24.99 and is used to add Alexa control to any outlet. The new Echo Dot is a significant improvement over the previous model, both in looks and sound quality. It’s available in Charcoal, Heather Gray, and Sandstone. If you just need to add Alexa to existing speakers, the Echo Input is still on sale for $19.99.
