Caleb's pick: My wife and I do much of our shopping online, which is great. However, our PO box  is usually crammed full of catalogs from the online vendors we use, which drives me nuts. It's a waste of paper, a waste of fuel to ship them and a waste of my time to deal with them. Once they enter our house, they languish on the counter or collect in the corner... Enter CatalogChoice.org, a site that allows us to create an account and opt out of catalogs quickly and easily.

Now what I do is I rip off the back cover (with the catalog name and our customer # on it), recycle the catalog right there at the post office and then go home and unsubscribe. We've just started using it, and have already seen our catalog infestation dwindling.

A word about them from their site: "Catalog Choice is a sponsored project of the Ecology Center. It is endorsed by the National Wildlife Federation and the Natural Resources Defense Council, and funded by the Overbrook Foundation, the Merck Family Fund, and the Kendeda Fund."
