Gulbi has been the most popular seafood for Lunar New Year and Chuseok holidays from 2018 to 2020, with sales totaling 663 million won, 734 million won, and 714 million won respectively. Other seafood such as blacktail, anchovy, squid, and mackerel also were highly sold. Abalone also saw a significant increase in sales, with Wando-gun's e-shop sales increasing by 270% and post office deliveries increasing by 67%. The rise in abalone sales is attributed to non-face-to-face marketing and online discount sales due to the influence of the coronavirus.
