Brazil has been a good arena for Android phones but Brazilians were never quite welcomed into the paid section of Google Play Store, with Gift cards that you and I use all the time. That is until now. Google is offering Brazilian droid users access to Gift cards in three denominations, R$30, R$50 and R$100 with account limit of R$1200.
That is enough to fill most of empty spaces on those android phones and more. More info and retailers carrying the cards on Google.
