Recently Google rolled out this new promo called Tap 10 where you use Android Pay to make 10 purchases in exchange for free stuff. Tap & pay once to get a free song from Google Music, 2nd transaction gives you another song, and so forth until you hit your 10th. Then you’ll get a free Chromecast. Sweet!
To get started or to get more info on this promo, simply open your Android Pay app. The new Chromecast is only $35 but your don’t have to spend that same amount to get one. There doesn’t appear to be a minimum to spend per transaction to qualify either.
The new Chromecast is what I use religiously in my home and Android Pay is super-easy to use. Definitely a great combination of using a Google service to get a free Google product.
