Go for Fortress or Broadway, they might charge a bit more, but they are hassle-free, and you usually get a bunch of free gifts on top.
For TVs, try AVLife a alternative. In general, go to price.com.hk as they are usually cheaper. I did for my dehumidifiers but that was because the high street stores did not carry the model I wanted. Admittedly, that is a pain for people without Chinese language skills. That said, there have been many instances where Broadway and Fortress offer specials that make them the no-brainer (eg last year I posted about the LG OLED tv being on sale there).
Electric Tung sell some stuff cheaper than Broadway/Fortress:

Sunying (sp.?) is also an option, and for us it worked out 3k cheaper for our tv than Fortress or Broadway.
The big box stores sometimes do have good deals with credit card companies that brings down their prices or offers additional freebies if you cannot find alternative suppliers
Recently a friend of mine bought a TV which is priced at $7-8K on price.com.hk but $11K+ at Broadway. He is not familiar with the shops on price.com.hk so he went to Broadway and asked the salesman there to match the price. He finally got some supermarket coupons and other free stuff including a nice sound bar and some other useless items. He said the sound bar and supermarket coupons are worth around $2k. So for you guys from overseas, try this approach and get better deals from Broadway and Fortress.
