if I buy from geekbuying the International Version that is not ES (I assume Spain) stock, will I pay customs to have it shipped to UK?
FWIW, re the original linked site (alibaba):
I did notice in the comments people requesting that the value be listed as nominal on the package. And they were getting individual responses from suppliers.
None of them on that site ship to Germany for some reason,** but do ship to other EU countries, and UK AFAIK.
Buying EU stock though would have it's advantages.
** I inquired and got a response in poor English that it was (something) to do with customs.
