Online daily deal provider Groupon, once the darling of Wall Street, has had its share of woes in recent months. Its stock is down over 50% from November's IPO price, thanks in part to a pending SEC investigation of the company’s Q4 2011 earnings restatement (actual net revenue was significantly lower when refunds to consumers for unused deals were factored in). In addition, merchants are beginning to pull back from Groupon, surveying their options in an increasingly crowded geo-local marketing landscape that includes the likes of Yelp, Google, Facebook, Amazon, Living Social and Foursquare, to name a few.
