with black friday and cyber monday sales, I'm sure things are going to be a bit backed up....also tracking usually is crap with anything coming from overseas....you'll get notified that a shipping label was created and then that it's at export....maybe notification when in import and then maybe when it's on it's way....
usually the only notifications I get is when the label is created and then when it's been delivered...everything else in between is just a mystery lmfao and that's with any site I order from overseas
hopefully though they can clear things up and let you know what's going on
but from experience with other companies, wait a month and if it hasn't arrived then start asking where it's at or for a possible refund.
(edit) just realized you said it'd been a week (when you posted) so um...well never mind, ignore me...
