They drove through the window and got away with thousands of dollars worth of electronics. The only thing they didnt take . The car. Stolen. Didnt need it. When the last time you checked your grocery receipt, you notice anything different . Getting overcharged the more common than you might think. In a story you will only see right here. Julywatts discovered safeway makes more mistakes than other california Grocery Stores. There is a policy if you charge lorer than the advertised price, you get the items free under 5. Reporter that is what customers are supposed to get when they are overcharged at safeway. The results of a 2008 lawsuit after a statewide investigation found the same thing back then we are still finding today. Widespread overcharges. We went shops at five Safeway Stores an were overcharged five times we compiled data from 31 california counties an 11 different states. In california alone, inspectors where overcharged on one out of every 50 items purchased over the past five years. A spokesman claims this is a store within the industry norm. Last year alone, their overcharge rate was 12 higher than other Grocery Stores statewide. It creates problem. Reporter the federal trade Commission Points to their short run sales. He says with more price fluctuation comes for opportunity for error. Changing prices all the time generates a certain level of confusion by consumers. And the store is the getting the benefit of that. Reporter a price he says the store is obligated to get right legally. None of this is top secret stuff. You dont have to figure out how to get the prices right. If the stores dont do it alone, agencies must do it. Reporter and thats what the state of california has attempted to do with three separate lawsuits. Since the most recent in 2008, records show is the supermarket continues to fail inspections by overcharging in three quarters of the counties. That doesnt include the counties that didnt allow us access. The remaining counties have done no inspections at all. At one point the do they step in and do something . I cant comment on whether or not there is any current ftc action on safeway or any other company. Reporter neither can the California Division of standards. But last year, they had a price verification survey. The Grocery Stores inspected were twice as likely to ere in their favor. By comparison. Safeway stores were four times as likely to overcharge. Thats according to county inspections conducted the same year. And scanner issues go far beyond california. Safeway is in 20 states. Inspections show higher failure rates in three other states, but california is the only state to take legal action and some have no inspections at all. The best way to protect yourself is to protect yourself. While they are responsible for protection at the national level. Newman says federal investigations can take years so its up to consumers to check their receipts. Those in california should hold safeway to the court order. All though it does take dedication. Ingly dont do that here. You know where its at. Reporter we spent a total of 30 minutes in Customer Service in three stores to dietary agains for three. Shouldnt i get it free . No. At the end of the day, only one store agreed. We can do that. Reporter now safeway says employees have since been retrained on the Court Ordered policy, but employees told us they were trained not to offer it for free unless a customer asks. Safeway says it is committed to eliminating all pricing errors and doesnt mean to charge over. They dont think our numbers reflect their errors. Lots of people checking their respites now.
