Not sure about this Walmart, but I believe it's 10 PM, especially for stores that close at midnight (like their North Brunswick store). You can try calling to verify, but some reps won't always pick up the phone at customer service even when they ARE open. (Once called the East Brunswick 24-hour store's main # and spent about 30 minutes -- possibly more -- trying to get a live person, only to get looped back to the operator, who seeing one's plight, reached out directly to customer service, only to be told by someone at customer service that they were WAY too busy and that they were REFUSING to answer any calls...). 😒 If you need to make a return during store hours, after customer service has closed, you can usually ask for a manager, who will then process the return at one of the registers.
As long as the store remains open.
Until Midnight
