Walmart offers the Disney Frozen Sing Along Elsa for $22. Opt for in-store pickup to avoid the $4.97 shipping charge. That's $3 under our mention from three weeks ago and the lowest price we've seen. (It's the best deal today by $8.) It includes a bonus necklace and sings the full-length "Let it Go" song when you hold the microphone up to the doll's mouth.
