Google is giving out a free movie rental to celebrate 2 years of its hit Chromecast streaming device! To claim the free movie rental, all you need to do is open your Chromecast app from your device and navigate to the settings page. From there, click on the menu and you will see the ‘Check for Offers’ option. It will ask if you authorize Google to check your serial number for offers. Your TV should display how many offers are available for your device. On your device, you should be redirected back to the Google Play store to save your offer. The offer can be saved and used by the end of this year. Enjoy!
