Local grocery stores are not online, their physical only presence means that during lockdown, people near the area have to go to the stores in-person. This has resulted in these stores (mostly small in space) becoming overcrowded with consumers.
Also consumers might have to wait a long time before they are able enter the store and buy products and often result in situation where some of the products they would like to buy are out of stock.
The opening hours of these store are not fixed.
