E-commerce accounts for more than 20 percent of retail sales in China, the highest and fastest growing penetration rate in the world, according to Mary Meeker’s widely-followed 2018 internet trends report.

With that challenge in mind, the Arkansas-based company is trying an experiment: A smaller store, focus on Chinese lower-tier cities and a new sales model with Chinese logistics company Dada-JD Daojia.
