There are several computer shopping malls in Hong Kong. One of the malls with the most convenient location and wide range of products is the one at Wanchai.
This is one of my favourite Hong Kong shopping malls. Its computer product range is very comprehensive and pricing is very competitive. This computer mall is always full of people as it is conveniently located next to Wanchai MTR station. To avoid the crowd, you might want go early or late. Shops opening hours varies, but most of them open in mid morning around 10am through 10pm.
Direction: MTR Wanchai station, exit A4, turn left
Shopping Tips:Though my experience shopping at this computer centre is good, and the shops here are generally reliable, but to secure that you are buying original products, please check the originality of the goods and make sure you won't buy any pirate goods.
