Clark’s mailbox gets filled every day with catalogs, most of which his family has never ordered. It’s like a new exercise program because Clark has to lift them out of the mailbox and carry them inside every day. Business Week published a story on how many catalogs people are receiving these days. You can stop these catalogs from coming simply by contacting the Direct Marketing Association or DMA. You can either sign up to stop the mailings online by paying $5, or you can write a letter to the DMA for free. The address is above.
