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.
