Google Play gift cards are now official and will be found at Radio Shack, Target and GameStop

Considering that someone had already mistakenly purchased a Google Play gift card last week from Target, it is no surprise that the cards have officially been announced by Google. Available in $10, $25 and $50 denominations, the cards can now be purchased at Target, Radio Shack and GameStop. Later this month, online buyers will find the cards for sale at Walmart.com.

Google Play gift cards can be used to buy premium apps, movies, music, books, virtual currency, extra gaming levels and special add-on packs.  For now, the gift cards will be available inside the U.S. only.
