Order a Santa letter online. If you're pressed for time and/or don't want to risk having your child recognize Santa's handwriting as your own, one option is using Santa Mail, which can send personalized Santa letters to your child with the official postmark from the North Pole. They also offer certificates to award your child for making it onto Santa's "Good List," in addition to other fun Santa-themed products that you can customize. They also guarantee delivery before Christmas and give customers a 100% money-back guarantee. For less than ten dollars, this may be the most convenient option during the busy holiday season.
