Guest Post Every morning, somewhere between 4 and 6 a.m., my inbox is assaulted by daily deal emails. This morning I fought back, feeling a sense of accomplishment as I deleted my last offer: 50 percent off a Brazilian Wax. Sound familiar? Groupon, the inventor of daily deals, has become one of the fastest growing companies in the history of the world. Much to its chagrin, Groupon seems to have created one of the fastest growing, most competitive industries in the world: 581 daily deal copycats now compete for your inbox.
