Once you've set up your Chromecast Audio, you can access and redeem all available offers for your Chromecast from the Google Home app on your Android device or computer.
If you see a "No offers available" message while checking for offers, there are no available offers at this time.
Note: iOS users must redeem offers from a computer.
- Make sure your computer is connected to the same Wi-Fi network as your Chromecast device.
- Visit g.co/home/chromecastoffer from your Chrome browser.
- Click Redeem and complete the redemption steps.
