The average spending by the holders of Shinsegae Department Store's new credit card for "lifestyle-oriented" men is seven times higher than other cards issued by the company that are predominantly used by women, South Korea's leading retailer said Wednesday.

The average expenditures stood at about 3 million won ($2,819) for a month after the Shinsegae Men's Life Samsung Card was launched March 2, the department store said.

The amount compares with about 400,000-500,000 won spent by the holders of other cards during the period. The store said roughly 70 percent of its card holders are women.

The latest findings come as men have become big spenders at luxury outlets and are expanding their presence in the retail market as a whole.
