Check it out. I joined today. You can select the catalogs you want to decline. Very cool.
Catalog Choice is a free service that allows you to decide what gets in your mailbox. Use it to reduce your mailbox clutter, while helping save natural resources. The mission of Catalog Choice is to reduce the number of repeat and unwanted catalog mailings, and to promote the adoption of sustainable industry best practices. We aim to accomplish this by freely providing the Catalog Choice services to both consumers and businesses. Consumers can indicate which catalogs they no longer wish to receive, and businesses can receive a list of consumers no longer wanting to receive their catalogs.
