Many of us were raised to believe that Santa Claus delivers our gifts before we wake up on Christmas Day. If you believe, behave, and send your wish list on time, you are virtually certain to receive what you want for Christmas. As we grow older, some of us (not me) begin to doubt the existence of Santa. But, with the growth of e-commerce within the last decade, no one can deny that more and more gifts are being delivered Santa-style. And for those who do not believe, well, the lesson has been costly.
