Just so you know, we haven't given up on the parcel posting thing. I generally try to get at least one in the mail every month, and if I am really organised, I'll send four in one hit. My personal aim is to send 10-20 per year, and to keep that up as long as we have troops deployed somewhere. So far, I'm not doing too badly.
I recently watched the two Four Corners episodes that covered Afghanistan. The second episode had a short segment showing the troops receiving parcels from home. It's amazing how much you can come to appreciate something like lemon teabags when you are a long way from the nearest supermarket.
