With the China Post boxes, do you have to take all your junk to the post office or can you take a box home, pack it there and then take it back to the Post Office?
I'm not having much luck getting a quote from SevenSeas, their website gave a generic quote from China to NZ for 1,215RMB but their list of cities in China that they deal with doesn't include Hailaer and I've had no response to my emails to them.
