If you are like me, your mailbox is overflowing with unwanted catalogs,and you have no idea how to make the onslaught stop. Americans are inundated with 19 billion catalogs a year. A new not-for-profit Website called Catalog Choice just launched today that lets you opt out of getting such mailings on a catalog-by-catalog basis. (The site contacts companies sending out the catalogs for you). Clear out your mailbox and save some trees while you are at it.
