Since I have posted this thread I was emailed a contact 'My Wine Man' (
info@mywineman.com) who I have contacted and he has sent me a list of his wines. (there was over 150 to choose from)
They all seem to be good prices, especially for the mid to high priced wines. He does seems to be removing the wine tax, and his prices are based on the relative strength of the HKD exchange , so you also seem to get good prices based on that. I have ordered a case of Oyster Bay (my favourite too) for $105 per bottle, as well as moet ($290 bottle). It also looks like you can save up to $500 dollars a bottle on high price wines (compared to Watsons etc).
I will post back once I receive my order.
