Walmart offers this Girls' 2-Piece Character Thermal Pajama Set in Hello Kitty (pictured), Disney Princesses, or Tinkerbell for $3 plus 97 cents for shipping. (You can also opt for free Site-to-Store.) That's $6 off and a very low price for kids' pajamas. Sales tax is added where applicable. It's available in sizes 4 to 10, but not in all size/style combinations.
