The Sonos One Smart Speaker is on sale for $199 for Prime Day. As if that wasn’t a good enough deal on its own, everyone who buys it will also receive a $50 Amazon Gift Card for free. That essentially makes the true price just $149, which is the new lowest price that this speaker has ever been. This deal is available for both the Black and the White versions of the speaker. If you like the idea of an Alexa controller speaker, like the Amazon Echo, but want something that sounds much better, the Sonos One is probably the best option out there.
