When you add a new method, Google Play will ask you to choose between credit/debit cards, PayPal, or carrier billing. Pro tip: If you’re a serial forgetter like me, set your default to PayPal—because at least then you get resale value from your old sneakers.
Enter your card details carefully, or link your PayPal account by following the on-screen prompts. Once it’s in, make sure you hit “Save.” You wouldn’t believe how many people forget this step and then get mad at Google. Don’t be that person.
