Import duties from creation

[xyz123]

Hi - am looking at getting a orient Mako and as usual Creation have the lowest price. In the past they used to offer an option of royal mail where it was said there is more chance of getting lucky with no import duty. but i cant see that option anymore. anyone ordered from there recently?

secondly how do i calculate roughly the import duties if i have to pay it? Will DHL express have their own charge?

thanks
