If you could ask a used bookstore owner a question what would it be?

I have a great used bookstore in my town and I have asked Kim to do an interview. I have a few questions, but would like to see if some of you would have any questions. If you have one please comment and if I pick your question, I will keep you name and when the interview is done and posted. I will give you one extra entry for the giveaway in that post.
