I recently posted an article about the web site you can go to, to opt out of credit card offers in the mail. I've made a full page on opting out. I have links to getting on the Do Not Call list, opting out of credit card offers, and opting out of Valpak coupon packs. When I find more, I'll add them to that page as well.
