"It was December 2014 when Korea Yakult introduced the first electric carts for "delivery ladies" as a way to improve its door-to-door sales service. There were many detractors in the beginning as the cart, which cost 8 million won (US$6,800) a piece, was too expensive to justify the investment. Nonetheless, the company has kept increasing the number of carts, reaching now the 5,000 mark. (17-06-2016, Korea Economic Daily)" Now it reaches 12,000 and ready to deliver ice cream bars.
