If you’ve recently used a self-checkout kiosk at Walmart (WMT) , and felt like your bill was abnormally high, (even amid inflation) then you were probably right. The retail giant has just admitted that it may have overcharged shoppers who opted to use self-checkout machines in March at 1,600 stores across the nation due to a technical issue, according to documents that were seen by Bloomberg News.
The documents reveal that the issue began on March 19, and that some customers were even undercharged for items across all categories such as food, apparel, etc. The source of the malfunction was due to an “internal system failure” that halted price data from being updated at self-checkout kiosks. Walmart’s tech staff were still tackling the issue two days after it started.
TheStreet has reached out to Walmart for a request for comment on what caused the technical error and how many customers were affected, but has yet to receive a response.
