Little Dress Shop is running a nice sale this weekend. Free shipping on all orders. Watch the sizing chart, my daughter is a tall-ish 6 year old and the Medium (3-5 years) dress is pretty long on her still.
$10 off $65 with code THNKU10
$15 off $100 with code THNKU15

I got a new Cinderella dress for my daughter (discounted) and three princess doll dresses for the AG doll (that she is getting next week for her birthday) for $57 shipped. Not amazing by any means, but I really like their stuff a lot and was glad to get a bit of a deal.
