Do you mind if I ask how you know what items a user has already bought?
Do you call getExistingPurchases() every time the app is started, or are you storing a list somewhere of what they have bought? Or a combination of both?

i don't check what they have purchased on the playbook. my app communicates via the 'net to a set of servers and those track the purchases.
