Groupon (GRPN -3.8%) is bleeding again today after William Blair downgrades shares to Market Perform in response to the company's poor Q3 report - Groupon now has a market cap of just $1.7B. Also, Reuters just took aim at Groupon, noting (among other things) a Raymond James survey in which 39% of merchants who used daily deals services said they don't plan to run another Groupon promotion, due to high commissions and low repeat customer rates.
