AFAIK, if it's under 60 quid total (including postage) there should be no duty to pay.
They take the utter **** with that handling fee though OP. Absolute WTF.
Sometimes you get away with it though. A few years ago, when I bought my twin pipe exhaust system from Japan, I paid about 60quid duty and fees. Despite that fact that the system cost, including express shipping, £1600!! I considered that a result!
