My son bought a Fortnite skin on his main account. With my credit card, which was okay, but he also wanted to buy "a Fortnite Skin" on his second account, but there was a message that there was no credit left on the credit card. Then I looked in the Ps4 store (for payment methods) what kind of credit card was there, and the message came up: 'This service can't be used with this account.
ask for help on how I can buy a skin with Mastercarde on the 2 account
