LEGO offers the LEGO The LEGO Batman Movie Arkham Asylum bundled with the LEGO Iconic Cave Set for $119.99 with free shipping. (The cave set will automatically add to your cart.) That's tied with our June mention of just the asylum and the lowest price we could find now by $30. This 1,628-piece set includes 12 minifigures and measures over 11" tall when assembled. The cave set includes a caveman and cavewoman figures.
