Well I'm guessing that people who know me will know about how much I love Christmas and the new Christmas meaning... Anyways, Amanda1 has just informed me of Buy Nothing Day - which is 29th Novemeber, this year (28th in North America). Anyways, there was a link on this site, to another initiative Buy Nothing Christmas. It's seems very Christian from the outside, but then it should do shouldn't it!? But there's still information for all you none beleivers in Christ who celebrate his birth!
So there you go, the site expains it all pretty well - read it and take note.
