So here is the deal. If you buy two Chromecast devices (that could be a mix of one Chromecast and one Chromecast Audio if you want), the bundle will cost you $55. That’s a good $15 savings off the top. Should you choose for the regular Chromecast (not the Audio), Google will also hand you a $20 Google Play gift card for each device. So you could buy two Chromecasts for $55, save $15 there, but then also see an extra
$40 $20 in Google Play credits from Google to spend as you please.
The $55 deal for two ends December 26. The $20 Google Play credits deal ends January 2.
EDIT: As some users have noted, it shouldn’t really matter where you buy your Chromecast from, you could still get all of these offers. I do not think that Google will withhold offers if say, you bought a Chromecast from Best Buy. I’ll have to refer you to the comments for confirmation on that. With that in mind, Best Buy is currently selling them for $5 off, or $30.
EDIT 2: We originally thought you could buy two Chromecasts and get $20 for each device, but Google says you are limited to “one per Google Payment account.” Full terms here.
UPDATE: Google just dropped the individual price of each to $30.
