need a good "where did you get my information?" answer

[Aaron Walker]

I just sent out my first batch of letters 3 days ago to a "pre-default" list (yellowletter.com) it is based on credit or something which is different from a 30-60-90 day late list. Since I am printing, stuffing, and mailing myself I only sent out 44 and have had 11 calls to my voice recording, 6 of which left messages....Im PUMPED because from what I hear, thats a pretty good response rate even though none of them were deal worthy.
Ok so my real question. What should I tell people when they ask " Where did you get my information?" I cant imagine that telling them I purchased their name from a list broker is the best reply. Any advise? Maybe I should find a script or something.

Thanks
