Grand Prize pulled at the end of the summer is a year of free movies for one child and a friend plus a subscription to Nickelodeon Magazine
Weekly Grand Prize - 2 movie passes for every child in your child's homeroom/classroom
Also - at the start of every movie they usually handed out a bookmark, candy, magazine or book to every child and they pulled 5 winners who got a prize pack (usually 3 books plus more candy

just what my kids need)
It is a great deal
For those outside of MA - National amusements also runs Multiplex Cinemas (sorry don't know what states)
