There's not one, but two Chromecast promotions going on right now that when combined end up being quite a deal. First off, Google is offering any new Chromecast or Chromecast Audio buyer $20 in free Google Play Credit to use for your choice of music, movies or apps. This offer is good for all new Chromecast purchases as long as they are activated by January 2nd, 2016. But that's not all. BestBuy is also offering their own promotion. You can save $5 on a single Chromecast (now $30 instead of $35) or $15 on two Chromecast or Chromecast Audios when bought together for just $55 for both. If you consider in addition to this discount you factor in the $20 in Google Play credit you're in effect getting two Chromecasts for $35...the normal price of one. The Google Play Credit is good no matter where you purchase your new Chromecast as long as it's activated by 1/2/2016. We've included the link below to Best Buy's Chromecast page where you can get this deal. Then, once your Chromecasts arrive simply set them up and navigate over to Google's Chromecast page to redeem for your free $20 in Google Play Credit!
