I will be passing through Changi airport in a couple of weeks, unfortunately on this occasion I won't have a chance to stay over in Singapore. I'm in the market for a new camera (probably a Nikon D60) and I'm wondering whether I should try to buy it at Heathrow before I leave or in Changi duty free on the way through. Are prices still as good as they were a few years ago (also taking into account the fact that my GBP won't go as far at the moment!)? Is there any way to investigate duty free prices on the Web? Any info gratefully received.
