Had a few things from US over the years but never really had a problem with customs, yes I have had to pay import duty, vat and parcel force but no major delays.
Two weeks ago I bought a Bell and Carlson stock, it was usps tracked, a couple of days state side to get to international hub, was in UK in less than a week. Its been sat in UK customs now for over a week with tracking just saying 'customs clearance. Has anyone else had this experience and is it just a case of sit and wait as can not find a number to contact to check up progress.
