My daughter is twelve and she doesn't shop online. I wouldn't think many kids under 18 would since they are not old enough to have credit cards. I would think the parents are doing more of the purchasing.
I don't know if this is possible/legal, but a lot of kids LOVE mail. I'm not sure how you would even go about obtaining a mailing list for children, (maybe try building an opt in list from parents you know???) but I think younger girls would be more inclined to look through a catalog addressed to them. Then they'll see stuff they like and ask their parents to buy it for them. My daughter always circles things she likes that she finds in my catalogs.
Price range is going to vary depending on the median family income of the area you're targeting.
Perhaps matching mother daughter sets is a good way to market to both.
Best wishes, Dawn
