Posted this as a comment in a deal thread, thought it might be useful for some people travelling to China/HK.
While prices are generally lower than Gearbest/Aliexpress even on sale, IMO GB provides a good service for shipped products to Aussie doors with some form of warranty, so I'd never expect them to match native Xiaomi prices by default.
Also I didn't go to Mi just to take down prices, so I've only listed what I bought or took interest in / notice of in the Shenzhen flagship store. There are some in-store sales compared to mi.com (CN).
Lastly, Xiaomi in China do a lot more than just what they're known for in Aus (power banks, phones, fitness bands) - they have loads of different home products (from every kind of home automation device to washing machines, AC units, TVs and soundbars), drones, electric scooters and go karts (!), luggage, and even a ukelele. Store is worth a visit just to check this stuff out, which all looked typical Xiaomi high quality from a basic first impression.
