Amazon offers Prime members the Disney Frozen Musical Magic 10" Doll in Elsa (pictured) or Anna for $29.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $4.44.) Although that's list price, these hard-to-find dolls are currently only obtainable on eBay, with most "Buy It Now" prices starting around $50. When you hold the doll's hand, it lights up and plays music from the movie. Plus, if you buy both dolls, they'll sing together in harmony.
