I have a box to fill with books from my shelf. Order 3 books and then send me a list of up to 8 or 9 more in order of preference. I will fit as many as I can in the box and send it to you. I will let you know before mailing which ones and how many fit. At least 8 books will fit in the box unless you choose all bigger books so you will get 8 or 9 books for three credits. First responder gets the deal. Thank you for looking at my shelf.
