LEGO Shop@Home is currently running a promotion where you can score a free polybag set of Iron Man vs. Fighting Drone. Just make a purchase of $50 or more and the set will be added to your cart automagically. Promotion lasts from May 16 through 11:59pm EST, May 31, 2013, or while supplies last. And in case you were wondering, this Iron Man is the same one you get from 6867 Loki's Cosmic Cube Escape. Now would be a good time to pick up those Man of Steel sets, or Iron Man 3 sets. Also, you still get free shipping if your order reaches $75 or more.
This deal is also good at LEGO Brand Retail except for the stores at Downtown Disney in Anaheim, CA and Disneyworld in Orlando, FL. Hey, I'm not making this up. It's in the calendar.
