We're no strangers to Chromecast deals around these parts, but this is one of the best we've seen: $20 in Google Play credit for free with your purchase.
The offer is available on any Chromecast purchased between December 7 and December 21 from a number of major retailers. If that weren't enough, Google is still offering two free months of Hulu+ with your purchase as well (available on the Chromecast offers page), which is worth $14 on its own. Amazon has the Chromecast for $32 right now, so assuming you have a use for these credits, you'll effectively be getting the hardware for free. [Amazon]
