Hi all,
My contribution to this thread .. after returning from HK today and has visited most of the popular shops in several area ....
Citicall, Fortress, broadway .... they have fixed price for all their outlets and the price is ok. Personally I highly recommend If you have no idea exactly which shop to visit
