The last figure I heard was 6000 books sold in under forty minutes. I don't have a final total though, and the books are continuing to sell on the HSN website. And RR will continue to make appearances and sell more books on HSN in the future.
As far as what kind of books RR wants to buy right now, you would need to ask the editors.
