On an upcoming trip, I'm flying from London to Hong Kong, spending a few days there, then carrying onwards to Australia. I've generally found the arrivals duty free stores in Australia to be fairly poor value, so I'm therefore planning to buy things before I arrive.
One option is to buy things in Heathrow, then pack it in my suitcase while in Hong Kong, before flying on. The other is to buy things in Hong Kong before boarding my flight.
The Heathrow duty free website isn't great, but it does manage to list the prices of many of the things they sell (but by no means all, or least not that I can find...) Fine for getting an idea though of prices, and pretty good on their special offers.
I've looked in the Duty Free section of the Hong Kong airport website, which lists where the duty free shops are, but I can't seem to spot prices either there or linked from there. Since I'll be in HK second, if I discover Heathrow was cheaper it'll be too late...
Is it possible to check the rough or exact prices of duty free alcohol in the Hong Kong airport online? Or failing that, does anyone know roughly how prices compare with somewhere like Heathrow?
