The relatively mild weather this winter has blurred the traditional seasonal boundaries in terms of sales of shopping items.
Fruit, ice creams and soft drinks, whose sales typically peak during the summer season, continue to draw steady demand at major supermarkets, while sales of leisure and sporting goods such as swimsuits and other outdoor items remain unusually popular.
Supermarket chain E-Mart said it saw sales of summer sporting goods jump recently, but sales of typical winter sporting items such as skis and snowboards declined.
It also saw sales of melons, usually only available during the summer, jump 62 percent on-year from December to January. During the same period, sales of imported pineapples grew 60 percent, while those of mangos and some other frozen fruits more than doubled.
