Google now has Google Play gift cards that you can buy at GameStop, RadioShack or Target. They can be used to purchase music, TV shows, eBooks, apps, etc. They can also be used to purchase extra levels, add-on packs and virtual currency.

“For developers, this means that your apps and in-app products can reach an even wider base of customers who are registered and ready to purchase,” Google said in a Google+ update.

The cards cannot, however, be used to purchase app subscriptions, magazine subscriptions, hardware, or accessories.

The cards are not reloadable, and can’t be combined with other non-Google Play balances in your Google Wallet account.

Don’t bother getting them for the kids (unless they’re teenagers). You have to be 13 or older to use one. You also have to be a U.S. resident. To redeem the cards, users must get Google Wallet accounts, and kids between 13 and 17 can only get an account is limited to redemption of the card.

The cards are issued by Google’s Google Payment Corporation (GPC) subsidiary, which handles Google Wallet in the U.S. They do not have expiration dates.

I’m surprised it’s taken this long for Google to get these cards in stores, as they could contribute immensely to Google Play purchases. iTunes gift cards have long been a popular gift item, and this gives Google a way to counter that for all of the Android users (and Google users in general) out there. They may want to get them in more stores though.

The cards come in $10, $25 and $50 options.
