I'd like to add $10 to my existing Google Play balance so that I can use the existing $21 worth of Google Play credit to pay for an annual $29.99 subscription.
I don't intend to buy anything else from the Google Play store and would prefer to only add $10. The minimum card value I was able to find is $20. Any suggestions where I could get $10?
Do you have another payment on your google account?
You can set it so it will prioritise google play balance and any remaining will be taken off your linked card.
