Perfumes selling in DFS Changi Airport

[chic.lush]

does anyknow knows whether the perfumes selling in changi airport arrival/departure is cheaper than those selling in those perfumes retail shops (those shop selling different types of perfume)? I guess if compare to the shopping centres cosmetic/perfumecounters, it should be cheaper. But how cheaper can it really be?

And my friends commented those perfumes sold in Changi airport, it actually last longer than compare to perfume retail shops ? is it true?

i have bought from DFS store before. it is about 10% cheaper than the retail counters in departmental stores.
haha maybe it's a psychological thing. to me, the perfumes all last the same regardless where i buy

btw, if you are looking for cheap perfumes, why not try online shops?
i am currently buying from an online perfume shop (http://justscents.livejournal.com/)

its prices are one of the cheapest around and they sell quality products
