Prices are different because as of now there still is no sales tax in HK - so the price is 'cheaper' ... I would say i saved an avg of USD200.00 per bag when I bought them in hK ... yesterday my DH bought me a new style white classic flap (the entire flap is lined in silver hardware) - and the base price was 1275 and with tax is was 1400 .... in HK i would have just paid the 1275
