If you enjoy playing Facebook games or checking out the latest apps, Facebook credits make it easier to purchase in-game items and premium features. While most games and apps are free, many offer special items for a price. To get these items, you pay real money for a specified amount of Facebook credits. In turn, the credits act as a digital currency.
Log in to Facebook.
Click "Account" and choose "Credits Balance." Alternatively, click "Account" and choose "Account Settings." On the My Account page, click "Payments."
Click the "Buy More" link in the Credits Balance section. A Get Facebook Credits box will appear.
Choose a payment method. Your options include PayPal, credit card or mobile phone.
Click the amount of credits you'd like to purchase. Choose the denomination of your payment. For most people, this will be "US Dollars."
Click "Continue." Enter your credit card, PayPal or mobile phone information.
Click "Complete Purchase."
