An investigation has found that Kroger overcharges customers on sale items. According to an investigation by Consumer Reports, FERN and The Guardian, items marked at a discount or on sale had price tag errors and shoppers were being charged more than they bargained for. The author of the study says he believes the issue is due to understaffing at Kroger stores. Here's what #Kroger has to say about the study. #groceries #onsale #sales #sale #shopping #investigation
