Target offers the Disney Frozen Deluxe Toddler 2-Pack for $37.99 with free shipping. That's the lowest total price we could find by $10. It includes Anna and Elsa dolls along with an Olaf figure that comes apart and back together again.
Of note, you can also bag the Disney's Frozen Sing-Along Edition DVD for free when you spend $50 or more on Frozen items. That's $15 less than other stores charge for this DVD.
