PlayStation Network (PSN) credits are a digital currency that can be used to purchase games, add-ons, and other content from the PlayStation Store. They can be purchased in various denominations, from $5 to $100, and can be used to make purchases on any PlayStation console or the PlayStation Store website.
Buying PSN credits is a simple and convenient way to add funds to your PlayStation account. It can be done through the PlayStation Store, either on your console or the website. You can also purchase PSN credits from third-party retailers, such as Amazon or GameStop.
