Something worth mentioning, maybe. I have in recent months bought a couple of basses from Japan. Both were sent via DHL, which was a little bit more expensive than other methods but not much. It took 2 days, door to door, from Tokyo - shipped on a Monday, paid the duty online on Tuesday, delivered Wednesday. The duty they calculated was less than the amount I had worked out and there was no handling fee. Not only was it delivered to my door, it was 're-delivered' as I was out when they tried first time - I got a phone call in the afternoon asking if I was in to receive it. Although I guess that was down to the individual driver.
Compare and contrast with Parcelforce worldwide who handled an earlier purchase from Japan. Tokyo to Coventry took 3 days. Coventry hung onto it for 10 days before rubber-stamping the paperwork. I then had to drive 30 mins to my local depot to collect it where I had to pay, in cash as they had no facility for card payments, the 20% VAT, 3% import duty plus £13 handling fee.
If I ever import a bass again I will make sure it is handled by DHL.
