This is Laurie Howell with The GreenScene. I'll tell you how. I learned my lesson about junk mail when I mail-ordered my Christmas presents one year. The next thing I knew, I was getting at least 20-catalogs in the mail every month. First I tried patiently contacting each company, but that didn't work.
Prevention is the key.
Whenever you order from a catalog, donate money to a charity, fill out a warranty card, or enter a contest, make it clear you don't want your name sold. And tell your credit card companies not to sell your name. You can also write a letter to the Direct Marketing Association in Farmingdale, New York. Tell them to add your name to the delete file. The folks who put it together really know their stuff.
