I got new information from the Porcelain Gallery in Seattle regarding H China:
"You can buy a Teacup & Saucer or Breakfast Cup & Saucer individually (not in a pair unless that is how you want them), but they are usually sent without the box if they are order in singles. The Bread & Butter Plates can also be bought individually, but again, are not in the orange box. Unfortunately, Hermes has decided it is cheaper to send out boxed items in two's."
It's good to know that you can buy the pieces individually and not just in two's... having said that, getting the orange boxes is half the fun.
