If you own a Chromecast then this news will surely brighten up your day! Google is giving all Chromecast owners $6 to spend in the Play Store, the credit can be used on movies, music, games or anything else in the store. All you have to do is head over to  the Chromecast offers page from your Chrome browser and share your Chromecast device ID with Google. If you’re concerned with giving your Chromecast ID to Google then here is the reason for why they need it:

In order to check for available offers, we require you to share your device’s serial number with Google.

We use the serial number to provide your device with offers that may be relevant to you. If you check for additional offers in the future, you will be asked again to provide your device’s serial number.

For more information about Chromecast’s collection and use of data, please visit the Chrome Privacy Notice.

If you haven’t redeemed any past offers then you can go back after redeeming the $6 credit and redeem any others that you would like. I have three Chromecast’s and was able to redeem the $6 credit three times so make sure you repeat the process for each Chromecast you own!
