The Google Chromecast and Chromecast Audio are a pretty sweet deal for the amount of device you get for your buck, but that deal just got better with any new purchase receiving a $10 Play Store voucher.
You can use the voucher to buy Apps, Games, or Movies for purchases made between February 3, 2016 and February 24, 2016.
You can use the Chromecast to connect to your TV using HDMI and cast video content from various supported apps on your Android device. Chromecast Audio is a similar concept, but specialises in streaming audio content to your connected speakers.
Presumably the promotion is only available to Chromecast units sold directly from the Google Play Store, so be sure to hit up the link below to grab yours.Buy a Chromecast
