Just launching in NYC today, this e-ticket outlet passes along exclusive, 50%-plus discounts on unsold tickets to a range of shows, from jazz gigs at Birdland, to stand-up at Comic Strip Live, to roller derby out on Strong I, to everything from Elton John cover bands to Poppa Chubby at B.B. Kings. In previous markets they've also coupled with pro sports teams, keeping your foolishly optimistic dream of $2k Yankees tickets alive.
