I posted a deal on these speakers at Best Buy a few days ago for $150 (they came out a few months ago with an original list price of $250). Well, the price has dropped again: Just $130 each on costco.com through 11/28/16 (Don't know if they're available in the B&M warehouse stores). Free shipping.
Here's some text from my other post:
This is a relatively new entrant into the wireless speaker wars. It seems to be situated to compete with both the Sonos Play:1 and the Bose Soundtouch 10, but up a half-notch in style and features. Unlike the Sonos, it includes bluetooth in addition to WiFi. And unlike either the Sonos or the Bose, it supports Google Cast / Chromecast, making it a bit more 'open source' in terms of the music and audio sources that it supports over WiFi. Like all of those, it can be paired with other speakers in a multi-room group. It also can operate plugged in or on battery.
It looks great on paper, but from the reviews it seems like it might not be quite as refined and ready-for-primetime as the Sonos or Bose options, so caveat emptor.
