Knowing the bandits who 'run' this country, it's probably Import Duty, Value Added Tax, You're Not Supposed to Enjoy Yourself Service Charge, Tax on the latter at 20%, Luxury Goods Tax, oh, and didn't it use a lot of diesel fuel to get it from the docks? Then let's tax that as well !
What, it came from Japan via a country where we've severed Diplomatic Relations? Embargo breaking - tax that at a further 20% !!!
Yet Revell can have a kit moulded in Poland, decals printed in Italy, packaging made and printed in Taiwan, parts boxed in France, imported into the UK from Germany, and still sell a new kit at a realistic retail price !
