Walmart experienced a system failure that resulted in incorrect pricing at 1,600 stores over several days in March. The error led to customers being overcharged for some items, particularly at self-checkout stands, with seasonally-adjusted prices being affected. The issue, which was documented in previously unreported files seen by Bloomberg, has raised concerns about the reliability of Walmart's pricing systems.
