The price of LCD TVs in HK is sky High..if you see the price in China or UK, US or AU, you will see a difference...
e.g in China.. I can see 47" full HD LCD TV at HKD7-8K...(Chinese brand).
If you search website in overseas.. take AU as an example. The latest Samsung 47"  LED LCD TV is around HKD15,000 only.  The Sony one is around HKD24,000...which is almost half price then the listed price in HK...

We should voice out to HK agents of Samsung, Sony, etc.

about a month ago...I check it in a Australia website....HK is selling over 40K...
