Diesel is right----snow affected some deliveries I was expecting, too. I'm not taking up for them, but consider the current snowstorm---New York has been buried. That means any deliveries they would be waiting on to fill your order could be stuck in transit. I know tractor-trailer deliveries have been draggingfor a good part of the last 2 weeks; airports have been cancelling flights left and right, so that affects air shipments. Outbound from their docks would have the same problem---the Post Office, UPS, and Fedex are all running slow.
I'd talk to them and see what they say----maybe take a look at what they promised for shipping time. I hate waiting around for my stuff to arrive, but it they tell me 5-10 business days, that means 2 weeks in real time.
