Yes, in the back of Once Upon a Toy at DD you can do the pony boxes. I think price was what above poster said. (Same as tater heads). My neice got 2 boxes last month which she stuffed 2 ponieswith sparkly hair that were different, a bed, little rain coats, shawl type thingys, tu-tus, blankets, a table, tea set items, a popcorn cart, ice cream mickey heads (like the tater ones but pink), a ballon (like tater ones but pink), princessess hats, crowns, shoes, & brushes.
It is great and what is weird is my cats love the pony stuff too. One of my cats carries a pony that we stuck multiple tu-tus on around the house like it is her baby - so next trip we'll have to get a box just for the cats.
