I contacted SpaceNK earlier for an update and got this e-mail:
Thanks for contacting SpaceNK
I completely understand that you're eager to receive your Advent Calendar, and I truly appreciate your patience.
This year has been especially busy due to the overwhelming demand for the Advent Calendar. Please bear with us just a little longer – our Distribution Center is working around the clock to get as many orders out as quickly as possible
As your order was placed on 12th September your estimated dispatch date is 30th September with a delivery method of 2-4 working days.
Rest assured, payment will only be taken once your order has left our warehouse. We're truly sorry for any inconvenience this may have caused and appreciate your patience.
I'm confident it will be with you very soon. Keep an eye out for the dispatch email, and thank you again for your patience.
Hopefully everyone will get their calendars soon.
