WalMart said on Wednesday it sold out of its massager and other massagers for the first time in a decade.
The sale comes as Wal-Mart has been struggling with an array of new products, including the launch of its own line of premium fitness trackers, and the acquisition of health app and fitness tracker maker Fitbit.
Walmart has been losing market share to Amazon and Google for years.
It was first acquired by Sam Walton, who later became a billionaire.
Walmart also has struggled to maintain its image as a destination for customers who want quality, but are looking for convenience.
