Toys'R'Us via eBay offers the LEGO The LEGO Batman Movie Arkham Asylum for $103.99 with free shipping. That's the lowest price we could find by $46, although we saw it for $14 less in September. This 1,628-piece set includes 12 minifigures and measures over 11" tall when assembled. The cave set includes a caveman and cavewoman figures.
