How to make purchases with wallet funds and other payment methods
When you pay for a purchase, your wallet funds are used first. If your wallet funds don't cover the full balance of a purchase, the remainder can be settled using other payment methods.
Each adult account has a wallet. You can add funds to your wallet using a valid payment method or PlayStation Store gift card. Wallet funds can then be used to purchase content and services from PlayStation Store.
If you’re making a purchase, any wallet funds will be spent first.
If you're buying a subscription with wallet funds, you may still be required to add a payment method to your account.
