Earlier this year, Walmart started to roll out two other app features that streamlined trips to the pharmacy and to its in-store money transfer desks. The company also started making its Walmart credit card available to customers via its Walmart Pay app as soon as they're approved for one. And Walmart Pay has been doing pretty well. A study from InfoScout showed that, behind Apple Pay, it's the second most tried and used mobile wallet in the US.

Walmart says that the new return process will be available for Walmart.com purchases beginning next month and in-store purchases in early 2018.
