I'm in Germany and I picked it up from the local customs office on the 2. January. Got a letter from DHL on Saturday, 30th December with the Customs Dispatch Note and the note to bring along the invoice.

I've found out that the USPS tracking number is on this Customs Dispatch Note right below the barcode. Entered it at the USPS website only to find out that my box left San Francisco/USA on the 20. December and arrived in Frankfurt/Germany on the 21. December. It then went into foreign customs on the 21. december, out of foreign office on the 22. december and it says Attempted delivery Abroad,  December 23, 12.00PM - no idea who tried to deliver the box and where since no Postman showed up at my door that day and I was at home since I had lots to do one day before christmas. From what I've heard later DHL collects the parcels for the local customs offices and delivers them all together, that's why it took longer to get the box from Frankfurt to me as it took from the USA to Germany ...

I'm sure your box  has already arrived it's just hard to find out where exactly it got stuck without the tracking number. Hope it shows up soon.
