I have been seriously peeved in the past by getting catalogs continuously from the same companies that I call and ask to stop sending me crap. I still receive stuff from a company that I finally had mark me as deceased! 
It kills me to pay to have my mail forwarded and then see my package arrive stuffed full of things I turn around and just chuck. It's not only a waste of money, but it is environmentally just plain wrong!!
So - this is the site that has cleared out the bulk for me as far as catalogs are concerned.
