Hi tamanna,
In terms of price, no doubt Paris is the cheapest. The list price in Paris is already less than that in the US or HK or Singapore. For eg, reissue 227 is
Euro1890 including tax (which you can get 13% tax refund if you're a non-EU resident). In HK, large reissue is
HK$26K. In US, it's
US$2850 before adding sales tax. In Singapore, it's
S$4.9K+ including tax. So, if you happen to be in Paris / Europe, go grab a Chanel no matter what!!
HK vs. Singapore - HK is cheaper I think in terms of list price. But if you're not a Singapore resident, I think you can get a 7% tax refund. So, I think you will need to do your math beforehand. I read from another thread that medium lambskin price in Singapore is S$4.2-4.3k+. And Matte black reissue in small (225) is S$4460, large 227 is S$4900+ (in HK, large 227 reissue is HK$26,000).
US vs. HK - I think US is cheaper than in HK in terms of the list price (before US sales tax). But I don't know about the price after adding the sales tax in the US coz HK doesn't have any sales tax. For your reference, a classic jumbo caviar in Hong Kong costs HK$20,000. 2.55 Reissue Size 226 is HK$24,500, and Size 227 is HK$26,000. I think in the US, US$2650 for jumbo classic caviar, US$2695 for Size 226, and US$2850 for Size 227, right? You can multiply the US$ prices by 7.8 to get the HK$ equivalent prices so that you can compare the difference in list price, and then add the corresponding US sales tax to compare.
Hope this helps!
