If there are any Singapore residents on this forum who have experience buying Margaret River wines and bringing them into Singapore for personal consumption in excess of the duty free limits of 2 litres of wines, I would be grateful for some instructions on how to make payment for wine duty at Customs at Changi airport. I understand it's $70 per litre of alcohol which works out to S$7.09 per bottle of 750ml at 13.5% alcohol. Is it generally worth the trouble? If not, I will just buy within the duty free limits to avoid the extra time needed to navigate Customs on arrival at night. Thanks!
