Sonos rarely discounts their products, and while Sonos didn't actually do this discount on the PLAY:1 (it was actually Amazon), it's still worthing taking note of and perhaps picking up one or two. Typically, the Sonos PLAY:1 sells for $199, and right now, Amazon is selling it for just $199, which is a pretty decent discount of around 10%.
The Sonos PLAY:1 is a great speaker to pick up and get started in the Sonos ecosystem. Sonos has gotten a big name for the ease of use with their speakers. These are wireless speakers that work with either Bluetooth or WiFi. When using WiFi, you'll get higher-resolution audio (since WiFi has better bandwidth than Bluetooth), and it's also easier to use. You can set up these speakers throughout the house and Sonos will play on the speaker that is in the room you are in. Sonos also has many other products available, including their new PLAYBASE which is their soundbar for your TV. Their speakers aren't cheap, but definitely worth the money.
Additionally, the Sonos PLAY:1 is also eligible for Amazon Prime's free shipping. If you are not a member of Amazon Prime, you can sign up for a free 30-day trial and take advantage of unlimited two-day shipping as well as the many other perks that Amazon Prime includes.
