South Koreans spent 12.2 trillion won on the country's top two food delivery services, Baedal Minjok and Yogiyo, last year, up 75 percent from 6.95 trillion won in 2019, according to the data from industry tracker WiseApp.
The increased expenditures were attributed to the stay-at-home trend triggered by the pandemic.
The combined transactions on the two services reached a monthly record high of 1.44 trillion won in December.
According to WiseApp, the data excludes those of other major food delivery services, such as Coupang Eats, which means that total spending by South Koreans on food delivery services last year is much higher than spent 12.2 trillion won.
Baedal Minjok has the most users with 13.73 million last month, trailed by Yogiyo at 7.17 million, and Coupang Eats at 2.58 million, according to WiseApp.
Last month, South Korea's antitrust regulator approved the $4 billion sales of Woowa Brothers ., the operator of Baedal Minjok., to Germany's Delivery Hero, which owns Yogiyo, on the condition that Delivery Hero sells Yogiyo.
Delivery Hero expects to receive final approval for the deal in the first quarter.
