BEIJING: JD.com, China’s second largest e-commerce site behind Alibaba, is rolling out a service with a leading Chinese supermarket chain that will allow shoppers to order groceries and fresh food and have them delivered to their homes within two hours. The service will begin later this month with 30 stores of Yonghui Super Stores Co Ltd in the Beijing area. Shoppers will have a choice of 1,000 products ranging from fresh produce and meat to everyday products like shampoo. The company said that it will look to expand the partnership in the months ahead. Delivery is free for orders over 39 yuan ($6), but JD.com is charging six yuan (94 US cents) for orders under that threshold.
