Groupon is, of course, an extremely popular coupon / daily deals website. However the stock has done nothing but crash since the company went public. So far the collapse has been even worse than Facebook's plummet when the went public. Groupon, ticker GRPN, is down over 50%, after going public, and now trades under $10. So what are investor's opinions on this one? Is it a good buy now that it's under $10 or will this thing go down even more?
