As Walmart continues to build out its e-commerce business to rival Amazon’s, its latest development will build on some of the retail giant’s most established operations: Walmart is launching a new in-store returns service called Mobile Express Returns.

People who purchase items online and then need to return them can do so by logging them on the Walmart app, generating a QR code for the transaction, and then walking into a physical Walmart store to return or exchange the items quickly. In certain cases such as orders with bulky items, customers can simply keep them and still get a refund, a program it referred to as “keep it” in an interview last week.
