Buying JPop in Hong Kong

[HanabiChick]

I'm hoping someone here can help me. My brother is currently living in Hong Kong, and my mother is going to visit him at the beginning of October. I want him to get me two albums and my mother will bring them back with her. As my brother doesn't have much free time, I thought I'd post here and get some names and addresses of places that sell the genuine HK versions of Japanese releases (the OS versions), because they're cheaper than imports, so that he'd be able to find them. The two albums I'm looking for are Every Little Thing's Crispy Park (CD-only version) and Mai Kuraki's DIAMOND WAVE (also CD-only). If someone could tell me where he'd be most likely to find them, I'd be very grateful. I've already got the locations of HMV, I just want to find out if there are more places.

Edit: I'm only looking for shops that stock the official CDs
