Kroger overcharges customers for items marked as being on sale, Consumer Reports finds

Kroger shoppers might be paying more at checkout than they bargained for.

A new investigation found price tag errors at the supermarket giant's stores leading to customers being overcharged on many items marked as discounted or on sale. Expired discount tags were found on everyday products ranging from Cheerios cereal to Nescafé instant coffee, according to an investigation by Consumer Reports, The Guardian and the Food & Environment Reporting Network (FERN).

The probe stems from allegations made by Kroger employees in Colorado who are currently in labor negotiations with the supermarket chain.
