While cleaning her house, Thanh of Ho Chi Minh City's Thu Duc District heard the doorbell and ran down quickly to see a supermarket delivery employee waiting for her.
She used to go to the supermarket to buy daily necessities when returning home from work.
"Now I work from home, and quite busy and afraid of going to crowded places for fear of COVID-19. So I choose to shop online," Thanh said.
Thanh is not the only customer to switch to online grocery shopping through apps launched by supermarkets or ride-hailing firms since people are required to limit going out and keep a minimum distance of two meters from each other in public places.
In fact online grocery shopping is booming.
A spokesperson for BigC supermarket chain said its stores in the south have reported 3,000 orders in March, up from 1,000 the previous month.
In the north, the average order value this week ưas up 80-120% compared to the past.
Hung, a delivery worker at a BigC supermarket in HCMC’s Binh Tan District said in the past few days the number of deliveries has increased by two to three times.
"Some days I have to eat lunch quickly and then deliver right away so that customers do not have to wait long."
Saigon Co.op has received over 20,000 orders though its online shopping service only began a fortnight ago, more than 50% through messaging apps like Zalo and Viber.
The Republic of Korea's retailer Lotte Mart’s e-commerce site SpeedL and supermarket chain VinMart also reported a surge in orders, with vegetables, fruits, rice, noodles, cooking oil, bottled water, and toilet paper being the most in demand.
Ride-hailing firms have caught up with the trend, launching new services that enable people to buy food and groceries without leaving home.
Ride-hailing service Be Group gets 15,000 orders every day for buying goods, up 200% from late January.
