Many stalls at the local malls offered discounts of 50-70 percent.
A shopping centre on Ly Tu Trong Street in District 1 was full of female customers.
People were asked to stand in line, complete health declarations and take temperature checks for Covid-19 prevention.
This year, the number of customers who hunt for Black Friday sales was lower than in previous years due to the Covid-19 pandemic.
Nguyen Hang, 22, from District 12, said she often takes advantage of Black Friday to buy products at cheap prices.
Most of the customers hunting for Black Friday sales are young people, particularly students.
Shops became more crowded at noon.
