There is a rather obscure observance known as Buy Nothing Day (BND) held internationally in protest of consumerism. The primary participants are North America, Great Britain, and Sweden.
It typically goes down on the dreaded "Black Friday" that historical first and largest shopping day of the holiday season. In other locations it may be held on the day after Black Friday ... which is the last Saturday in November.
Regardless of your consumeristic bent, I hope you enjoy either day participating in your lack of consumerism ... or reveling in it along with the rest of the fray.
