App Center: What payment method can I pay with? Can I get a refund for my App Center account balance? Can I get a refund for my account balance? How can I pay for new digital content in the App Store? How does automatic leveling work in Leapster Explorer and LeapPad games? I can’t buy Expansion Packs or Apps in the LeapFrog App Center. I get the error that says “Oops! No products linked to this account..” Where is the app I just purchased? Why does an app show as “Not available” for purchase in the App Center?
