At $35 the Google Chromecast is a hell of a deal, but Best Buy's sweetening an already sweet pot. Right now if you buy a Chromecast it comes with 2 months of Hulu Plus and 90 days of Google Play Music All Access, which is $46 worth of content — but if you buy a Chromecast from Best Buy they're throwing in $20 worth of Google Play Credit so you can stream a movie or two to get comfortable with your new little dongle. Add it all together and you get $66 worth of free subscription and download content and a Chromecast for just the $35 cost of the Chromecast.
