At Ticketmaster, buy one ticket for select performances nationwide and get a second ticket for free via coupon code "TMN241". (Enter your ZIP to choose your area. After choosing your event, select this offer under ticket type. Available seats will display once you've entered the code.) That's tied with last week's mention as the best offer we've seen from Ticketmaster this year. Tickets can be purchased via "Print at Home" or "Will-call".
