Groupon, the online deals site that was once the darling of both Wall Street and the Chicago tech scene, continues to stumble. On Monday morning, its stock price fell another five percent -- and that came after a 30 percent drop on Friday. The stock has now lost 90 percent of its value since its initial public offering last year.
Groupon is a great way to cannibalize your business by giving away your product for free without ever turning those customers into non-discounted repeat business. Couldn't happen to a nicer company that is not named "Yelp".
