$20 Google Play credit
one section of the Best Buy description states:
"Good for one $20 Google Play credit"
whereas another section states:
"$20 Google Play Credit
Enjoy $20 in streaming movies from Google Play when you buy Chromecast."
question i have is whether or not the $20 credit has to be explicity used for a movie or can you use the credit for books, software, etc. from the Google Play store.
thanks!
