Well is the lazy two Ks at the PO can't even get a 1st class letter 40 miles in less than a week (posted 03/12 received 17/12). Then I reckon you should get the cart around 5th of January if they really pull their finger out.
Well you've got customs flunky and PO twonk who will need time to unpack their nose, scratch their butt and drink tea before thinking about processing the package. Then a week to 10 days for the customs duty and PO handling surcharge letter to reach you before they actually get rounto thinking about delivering it.
