In transactional / middle-men businesses, it's more standard to only report your percent take as "revenue", rather than including pass-through dollars (e.g. PayPal only reports their fees as revenue, not all dollars that flow through PayPal). But I suppose it's unclear if Groupon is that kind of business; arguably they could be more like a retailer, where it is standard to include all dollars flowing through as revenue.
