Don't even think about buying these on eBay unless the shipping is free and the basic prices are as I have listed below. The prices are all over the map. There is a 19" resin (polyester) China Doll who is a limited edition of 500 that is being sold for extraordinarily high prices- averaging about $500 more or less.
All four witch dolls and Oz holding the tiny China Doll are $19.99 each on Amazon and at Toys-R-Us. Free shipping included. The 14" China Doll is $21.99. There is also a 4" China Girl listed at $18.47.
I do not see the 4" at Toys R Us, however.
I have admired these dolls since I first saw them and I am ordering them just for fun. (aka lack of impulse control)
They are articulated and I'm hoping the fashions are not sewn on.
BTW, Theodora's fashion in the movie was to-die-for. Her pants were leather and super tight. Mila Kunis is a stunning woman. The movie was sort of fun but don't expect fine acting. Watch the original Oz if you want a truly great movie.
