as far as im aware, I think this is how you work it out...
•Theres a [b]3.5%[/b] Customs Duty charge on the total cost (Item Cost [b]AND [/b]Postage)
•You are then charged [b]17.5%[/b] VAT on the new total cost (Item Cost, Postage [b]AND [/b]Customs Duty)
•Finally, you are charged a Clearance Fee for "handling and administration". This is [b]£13.50[/b] for express parcels (delivered via Parcelforce), and [b]£8.00[/b] for all other parcels (delivered via Royal Mail. This used to be £4.00 but was recently increased...).
The equation:
( ( Item Cost [b]+[/b] Postage ) [b]x[/b] 1.035 ) [b]x[/b] 1.175 ) [b]+[/b] £13.50 [b]or[/b] £8.00 [b]=[/b] Final Cost
Im not 100% certain this is accurate, but im pretty sure... Anyone feel free to correct
