The Walmart-JD omnichannel shopping festival held in China on Aug. 8 produced a 13-fold increase in the combined transaction volume for Wal-Mart Stores Inc.'s e-commerce channels on JD.com Inc. compared to the previous 24-hour sales record.

The Chinese e-commerce company said Wal-Mart's physical stores also saw a "significant" increase in consumer traffic. The average basket size across JD's Wal-Mart flagship store, Wal-Mart global shop flagship store and ASDA global shop flagship store was double the average in July.

Female shoppers accounted for more than 50% of shoppers during the event, with Pampers, Jinlongyu, Great Value, Lego and Nestlé the most popular brands. Imported products on JD.com were also popular, led by U.S. toys, Australian healthcare products, British foods, Korean facial masks and Japanese diapers.

The pilot integration of JD.com and Wal-Mart's inventories in Shenzhen, China, helped cut the average order delivery time by three hours during the shopping event, the company said.

On Aug. 8, JD.com's JD Daojia delivery platform received three times the average daily order volume recorded in July. The fastest delivery was completed in 15 minutes.
