A monthlong Consumer Reports (CR) investigation alleges that shoppers at almost half of Kroger-owned grocery stores are overcharged for sale items. The investigation began after CR learned that Kroger workers in Colorado alleged widespread errors in pricing labels during union negotiations.

In an effort to document the "size and breadth of the problem," CR recruited people to visit multiple stores in multiple states over several months. The results?

“The shoppers found expired sales labels that led to overcharges on more than 150 grocery items, including Cheerios cereal, Mucinex cold and flu medication, Nescafé instant coffee, boneless beef, salmon, and dog food,” the report stated.

How widespread is the issue?

According to the report, CR recruited people to visit 26 Kroger stores — including Kroger, Harris Teeter, Fred Meyer, Fry’s and Ralphs — across 14 states and the District of Columbia during March, April and May 2025.

Shoppers documented more than 150 items where expired or misleading sales tags could have caused customers to pay more at checkout than the price listed on the shelf. Roughly one-third of the tags were outdated by at least 10 days, and several, they say, expired months before.

The average overcharge was $1.70 per item — or, 18.4% more than the advertised sale price.

“People should pay the price that is being advertised, that’s the law,” Consumer World founder Edgar Dworsky told CR.

“The issue here is that shoppers can’t rely on the shelf price being accurate, and that’s a big problem.”

Items affected included a range of household staples and name-brand goods such as cereal, medication, instant coffee, meats, seafood and pet food. In some cases, the shelf tags still displayed promotional pricing well after the sale had ended, potentially misleading shoppers into thinking they were getting a discount.

One example, KTLA News reports, was an 8-pack Mission Flour Tortillas advertised as on sale for $2.99 but showing as $4.00 when the CR shoppers checked their receipts.

A Kroger representative responded to the report, saying the company regularly checks prices for accuracy and called the CR report a “few dozen examples across several years out of billions of customer transactions annually.” The company said that while no errors are acceptable, characterizing a few mistakes as "widespread pricing concerns" is false.

While Kroger is the latest retailer to come under scrutiny, it’s not the only one. Other chains, including Walmart and Vons, have faced similar accusations in recent months. In October 2024, Albertsons agreed to pay $4 million to settle a lawsuit that accused the California grocery chain of charging more than the lowest advertised price for various items.

Consumer advocates say the issue may be more common than most shoppers realize, and without checking receipts and shelf tag dates, many overcharges can easily go unnoticed.
