I found an organizer box that's great to easy transport of the WotR:CE bits (not that it's not great fun to haul around that huge wood book box).
This box is a Stanley "Professional Organizer" and ran about $13 at Target. I switched a couple compartments between two of them to give this one a few more midsize compartments and a few less small ones. Everything fits! You can separate things out a bit more if you don’t include the expansion components.
