Has anyone here taken advantage of Local Deals sites (Groupon, LivingSocial, LifeBooker, or even the less popular ones)? How did it help or hurt your business? Did it make a difference at all? I am considering offering a volume order deal, but I'm trying to match it to my services in a way that makes sense. I have also heard that these sites can backfire if you haven't planned for production costs of large orders.
