I have an Amazon.com box, dimensions are about 15 by 11 by 7 inches. Fill the entire box for 3 credits - start by choosing up to 7 books from my shelf or from my unpostables list (in my sig). If that doesn't fill the box, I will let you know how many more books to choose to fill it. I would guess this box can hold at least 10 books if you don't choose a lot of hardcovers. And there are some wish list books in my unpostable list...

First respondent only.
