"The current closing down of Giant and Aeon Big has nothing to do with disruptive technology as total online sales in Malaysia is hardly 5%.

And online sales of groceries / toiletries / fresh and sundries (which is 80% of a hypermarket business)  is hardly 0.5 %  in Malaysia

Also note the closing of the Giant branches are not in key urban areas like Klang Valley.

This actually shows rural purchasing power is gone down drastically
Business is down by 4.8% in hypermarkets which caters to middle and low income population,  simply because purchasing power for basics necessities  is down."
