Do Groupon, ScoutMob, KGB Deals and the other sites still not quite fill your need for group discounts in New York? This week brings the launch a new site of a slightly different tilt: MindBodyGreen focuses on flash sales for healthy, organic, green or otherwise crunchy offerings from spas, restaurants and the like. The introductory offers today include a 10-person Pilates session at Body Tonic in Park Slope and $10 off GustOrganics, the city’s first and only certified organic restaurant (located near Union Square). Co-founder Jason Wachob (a DUMBO resident) says the site will focus on “everything from vegan/organic restaurants, to yoga and Pilates studios, to events and more.”
