According to a support documentation, starting October 27th you will not be able use a credit card or debit card or PayPal to buy games or add money into your wallet on these systems. You will need to purchase a PlayStation Store gift certificate or load up your wallet on your PlayStation Store account via the internet, on your phone or on a PS4 and PS5.

Sony had announced in March that it would close the PlayStation Store for Vita and PS3 but reversed its decision a few weeks later. On July 6, Sony said that it would end all PlayStation Portable purchase functionality. This means that you cannot buy DLC for PSP games.
