Amazon celebrates Echo's 2nd birthday with $40 price cut

If you've been on the fence about getting an Amazon Echo, today's your lucky day. Amazon is slashing $40 off the voice-controlled tube, bringing the device down to $140 from its regular price of $180. The limited time discount is in celebration of the Echo's second birthday. The smart home controller/speaker launched in late 2014 to Amazon Prime members through an invite-to-buy system. Since its launch, the Echo has gone on to become a hit for Amazon and consumers.
