>>5974159>>5974560 looked it up on toys r us$24.99 doesn't seem outrageous at all for a doll that comes with three complete profession themed outfits, all of which include shoes, fashion accessories, and prop accessories. These aren't "tiny, pointless, gimmicky extras' at all.
Not to mention the dolls you're quoting aren't sets like this one, they're single dolls that come with a single ensemble with some nicer fashions (helmet, separates, etc) compared to Mattel's normal play offerings, so it's unlikely they'll be at the $24.99 price point.
