I open the box right away. My son will take a glance and grab a book or two, usually a science book, but that's it. He's not overly excited. I take out the invoice and grab a highlighter. I go through each box and mark off the books on the invoice. After I have checked to make sure the order is correct, I put the books back in the box until I have time to put them on the shelves. Have fun! I really like Sonlight!
