RiosinghFor continental Europe i have experienced no duties or taxes in the 10 things i have bought (6 watches). Why? Stuff gets re-labelled in Germany, so it is seen as bought from that country.
RiosinghFor UK then it is a hit or miss. In continental Europe all packages I have received (spaniard here) do a stop in Germany (I have received 11 so far), and they get re-labeled there, which means that our national custom considers it a continental Europe product and thus there are no duties to be paid.
So long as this relabeling does not change, I'd expect this to remain the same (for me). The day I have to pay duties will be the day I say bye-bye to Massdrop, I'm afraid.
