If you selected to buy Facebook Credits while using an app, you most likely used a portion of those credits to purchase an item. If so, you should be able to view your remaining balance in your account. The following example below may further clarify:
- A user wants to purchase a "Premium Island" on Happy Island for 149 Facebook Credits but does not have any.
- User is prompted to purchase 200 Facebook Credits.
- After successfully purchasing the "Premium Island", the remaining 51 Facebook Credits will be added to their account balance.
- A user can view their remaining Facebook Credits balance on the Payments tab in their account and use them for future purchases.
