Tired of receiving credit card offers in the mail? Me too. I found a way to opt out of these offers. Either call 1-888-5OPTOUT (1-888-567-8688) or visit optoutprescreen.com. The web site doesn’t look legit, but it is. I called the number and they even gave that URL in the phone message. How do I know the phone number is legit? I looked it up on some of the credit company web sites.
