Save yourself from unwanted mailings, help the environments

Catalog Choice (via DailyKos):

You enter your personal information, check off the catalogs you receive from a list, and they contact those merchants and ask that they stop sending you their crap. And the real impact of participating and spreading the word could be huge.

Indeed, just by signing up you can both reduce the number of unsolicited catalogs you're getting and reduce deforestation and global warming. It's a great deal. So please do your part to avoid stuff like this.
