Rice University recently came out with a study that brought up some concerns about the sustainability of daily deals’ providers. It indicates that daily deals’ providers would have to lower their profit shares in order to succeed and would still face the challenge of bringing in new merchants. However, a second study from ForeSee Results contradicts the one from Rice University since it shows that daily deals’ providers, and specifically Groupon and LivingSocial, are bringing in not only new customers, but existing ones as well.
