The Grocery Store Tricks Designed to Make You Spend More Money

The newest tricks aimed at grocery shoppers rarely happen on a physical shelf at all. Instead, they are running quietly through the same loyalty app being used to save money in the first place.

Retailers have collected shopper data for years, but the technology behind how that data gets used has changed considerably. Prices themselves can now shift from person to person, sometimes based on far more than just a coupon or a sale.

None of it requires breaking any obvious rule, at least not yet everywhere. Here is how the newest grocery pricing tricks actually work, and why regulators have started paying attention.

Your Loyalty App Might Be Charging You More, Not Less

Dynamic pricing, sometimes called algorithmic or surveillance pricing, uses personal data like browsing history, location and even inferred income or family size to set individual prices or discounts, according to Consumer Reports research cited by Moneywise.

An investigation into grocer Kroger found the company collecting detailed profiles on shoppers, including income level, education and family size.

Kroger has maintained it does not personalize the underlying price of products, only which discounts a given loyalty member sees. Even that distinction still means two shoppers buying the exact same item can walk away paying noticeably different amounts.

One Company Already Got Caught

Grocery delivery platform Instacart ran a pricing test that showed different shoppers different prices for the exact same products from the same store at the same time, according to a Consumer Reports investigation from December 2025.

Some shoppers were shown prices as much as 23 percent higher than others buying identical items in the same moment, according to reporting from Food Trade News.

Instacart discontinued the specific technology behind the test after the investigation went public. The company separately agreed to pay 60 million dollars to settle FTC allegations that it used unlawful tactics that raised grocery costs for shoppers.

Lawmakers Are Starting To Push Back

“Surveillance pricing can drive up the price of food,” Grace Gedye, a senior policy analyst at Consumer Reports, said in a statement reported by FoodNavigator. Maryland became the first state to pass a law banning the practice in 2026, with California, New York and Illinois exploring similar legislation.

These new laws generally target pricing based on personal surveillance data specifically, not traditional loyalty discounts or seasonal sales. The distinction matters, since ordinary coupon and rewards programs are expected to remain completely unaffected by the new rules.

None of this means every loyalty app is secretly overcharging every shopper. It just means the price on a screen is no longer necessarily the same price the person standing next in line is seeing, and that gap is exactly what regulators are now racing to catch up with.
