Walmart offers The LEGO Batman Movie Mr. Freeze Ice Attack Playset for $15.99. (Target charges the same via pickup; Amazon also has it for the same price via Prime.) Opt for in-store pickup to avoid a $5.99 shipping fee. That's the lowest price we could find by $4. It includes 201 pieces, with 3 minifigures: Batman, Mr. Freeze, and a security guard.
