I am writing a game where you will be able to purchase "chips" to buy stuff ingame. The problem is with consumables how do people keep track of what they have bought? For example if they purchase x amount of chips and then buy item y how can this be syncronised across all iDevices running my app so they all have item y?
I would really prefer not to have to hire or purchase a server to keep track of this information. Can Apple do this for me? Is it part of the in-app purchase API? What about using GameCentre or OpenFeint?
There must be a cost effective and simpler way to do this. Any advice would be appreciated.

Just a local database could easily keep track of purchases every time they do it. As long as you update the database whenever you call that method that does the purchase. No server required.

How does that syncronise the purchase across multiple iDevices?
What happens if the game is deleted and re-installed?
