Glad I'm not the only one. Ordered 11/28 and after three weeks had not received it. Only received an error when I tried to track through their website (with DHL). Contacted them a couple weeks ago and they sent a replacement, but still have not received. They opened up a claim with USPS (got a letter from USPS asking me to confirm I never received the package).
Happy with Pack & Smooch's customer service so far, so I am giving them the benefit of the doubt. There may be an issue with these getting cleared through customs. Probably backed up on the holidays (just a guess though). I guess I will just wait a couple more weeks and see what happens (I'm in Hawaii).
On a kind of related note, I order a lot of items and this year has been worse than most. Counting this issue, I have had three other packages lost in the mail and spent a lot of time trying to get my items (from different companies). So I may be more willing to wait a bit.
*Edit* Just entered both my tracking numbers manually through Deutsche Post website and got the following message: The item was handed over to the International Logistics Center Frankfurt on Dec 22, 2016 to be forwarded to United States of America. Further tracking information is also provided by the website of the country of destination.
So it looks like my earlier thought may be correct and the packages are stuck in customs. I get special alerts through USPS for all packages shipped to my house, and nothing has appeared yet.
