Many times online merchants do not stock the goods they sell. These are dropped shipped from the manufacturers directly to you. I wonder if with an overseas shipping address the system was unable to do so? I've ordered stuff from Amazon books, camping stuff, marine stuff on one order and have had it delivered on different days, in different packing and with different shipping labels. Any way, good luck!
I agree that this could well be, but his emails to the .com company should have confirmed that there is a delay in shipping part of the shipment. The fact that they are not responding likely what is causing the real issue here. I just ordered some camera stuff that was very cheap, and it took 30 + days to get to me, but it was communicated and I understood so I was not upset.
