Klarna's in-store push with lululemon targets $28 trillion physical retail

"We've spent years making online checkout smarter, and now we're bringing that same freedom to the till," Klarna Chief Commercial Officer David Sykes said in a statement. "Shopping shouldn't be less flexible the moment you walk into a store."

The in-store rollout comes as Klarna pushes beyond e-commerce, where it has built its brand. Global in-person spending is estimated at about $28 trillion a year, nearly four times the amount spent online, according to industry data cited by Klarna.

Lululemon integrates the payment option through its existing setup with payments platform Adyen.
