When Groupon was said to have turned down a $6 billion acquisition offer from Google, many onlookers wondered what could possibly have motivated that decision.  Now we know: the ability to earn $760 million in revenue in 2010, along with the goal of bringing in over a billion this year.

Groupon CEO Andrew Mason apologized to users in Tokyo for a deal that went bad a few days before the New Year’s holiday. The deal involved the delivery of food, and became too popular for the business providing the deal to handle.

They sold 500 "Groupons", and the business was unable to process the orders, leading to late deliveries, and deliveries of product in "terrible condition", as Mason describes it.
