Leveraging the power of groupon for in app purchase sales

Hi,

I have an app in the App Store that is free to download with in app purchases that allow the user to buy credits in order to buy in app content.

What I would like to be able to do is to somehow sell the credits at a discounted rate if purchased via groupon leveraging the wide reaching marketing capabilities of the groupon brand.

I am trying to understand if this could be achieved in anyway without breaching apples terms and conditions? Maybe the user purchases a discount code for a % off the purchase of in app purchases from Groupon.

Please can anyone describe an approach?

Thanks.
