Not sure how relevant this will be here, but I buy a lot of stuff from Japan (I'm in the UK) that gets shipped via DHL.
Takes 2 days to get to me (unless it gets shipped on a Thursday/Friday, then it gets delivered the following Monday) - one day from Japan to Germany, then it gets to the UK on the same day or early the next morning, clears customs, makes it's way to my local depot and then out for delivery by 8am.
Seems odd that it's taking so long for you guys tracking to update - I take it it's still shipping info recieved in the Netherlands for DHL people? Did your orders ship on Thursday or Friday? I can't remember
