$20 Google Play credit

The $20 Google Play credit can be used on anything in the Google Play Store, at least from my own experience. I used the $20 credit to purchase a few songs and a movie. Just a little more information for you: I had some trouble receiving the $20 Google Play credit. After buying the product from Best Buy, I did not receive a code in the box or via email for the $20 credit. After a week I called Google customer service first, since the code was to be used in their domain anyway. Google said they stopped offering this promotion before 2015, but Best Buy was still running a promotion for Google Play (although somehow "separate" from the expired Google offer....?). Either way, I called Best Buy customer service and they provided me with a code via phone within 2 hours. You must purchase the Chromecast from Best Buy to receive to $20 Google Play credit as of 2015, and your code will NOT be provided in the item box. Since I ordered my Chromecast on Bestbuy.com, their customer service was able to verify my purchase date, order number and contact information very easily through my online account which sped up this process. They were very helpful and knowledgable.
