Gchee is right, just the GST and handling charges. If you are buying Sinns you have to be a little careful as the authorised resellers may not handle your order as it comes from a country where Sinn is represented. Very leceh I know but that's what it is. A long time ago when I was in Frankfurt, I visited Sinn to buy but they say cannot as I come from Malaysia which is represented! Can you beat that?
Also please note you take a risk in getting your watch stolen in transit....it does happen, so insure adequately and get buyer's protection. Not encouraging I know but better be safe, Good luck!
