LivingSocial, headquartered in Washington D.C., is the second largest group buying website in the United States after Groupon. LivingSocial has over 1000 employees in 6 different office locations located in Washington D.C. But what is more flexible than its biggest competitor Groupon is that Livingsocial does not set a minimum number of group buyers. Users don't have to worry about losing the opportunity for discounts due to a small number of group buying participants. In addition, to encourage more users to participate in group buying, Livingsocial also launched a brand new "promotion for free" model at that time.
