I was thinking of purchasing some COMET bulbs from US and suddenly wondered if there was additional DUTY and TAX that would be applied - anyone any experience on this. Only asking as I just purchased 3 battery boards (to replace the AA holders) in my Bally and Williams, which all together cost me £35 (+ £11 postage) and I received from Royal Mail card informing I had to pay another £31 duty!?! - I feel I need to challenge.
