After I bought a bottle of Hugo Boss perfume at a Shanghai's mall, I was thinking next time I should buy it at airport duty free shop. The price should be at least 30-50% cheaper. Yesterday I was in Singapore Changi airport. I checked the price. Surprisingly, the price is almost the same as I paid in local stores. Is it real duty free?
