Google Play now offers giftcards to be purchased at RadioShack, Traget and GameStop. For iTunes users giftcards have been a great item to buy for your use or as a nice gift. I always enjoy getting iTunes giftcards, but the Android device users have been left out in the cold up until this point. The Google Play Store offers Apps, Books, Movies and Music. This is a great step for Google and opens up more options for their consumers.
Are you planning to purchase Google Play Giftcards? Will this veer you towards Google Play, stick with iTunes or both?
