Tech glitch may have overcharged Walmart shoppers at self-checkout

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.
