On October 2 and 3, participating LEGO Stores retail locations will offer a LEGO Witch Model Build for free when you register via this form as part of its Monthly Mini Model Build Event. (Kids will learn how to build the mini model and then get to take it home.) This event is open to children ages 6 to 14 only and valid while supplies last (about 120 sets per night, per store).
