Stop those stupid credit offers after all. Did you know they 'prescreen' you and send you offers only if they like what they see? Sounds obvious to me, but I think this is bigger than meets the eye.
Stop receiving "pre-screened" offers of credit in your mail for 5 years. I just did it.

Note: This may actually help your credit. This number should be displayed on all your credit offers.
