I want to know why Bungie needs my postal code. I was about to sign up for their feedback program, which I'd love to be a part of, but I'm very uncomfortable just handing out my specific location to anyone, unless it's business or finance related, because I get enough junk mail as it is. For example, are they going to send me promotional items like flyers (if that's the case, why just e-mail them), or is it just to know where I am? How are they going to use that information? Any information will help greatly.
