If your grocery bill feels unpredictable lately, it may not be just inflation at work. A new investigation suggests that some shoppers are paying more than others for the exact same groceries — even when buying from the same store at the same time.
According to newly-released findings from Consumer Reports and two partner organizations, Instacart routinely charged different prices to different users for identical items. The study found that these price variations could add up to as much as 23% more per order, potentially costing a typical family of four about $1,200 a year in higher grocery bills (1).

The findings shine a spotlight on how “dynamic pricing,” long familiar in travel and entertainment, is quietly making its way into everyday essentials, including food.
How Instacart’s pricing works and where retailers stand
Consumer Reports researchers created multiple Instacart accounts and shopped simultaneously for the same items from the same retailers. What they found was consistent price variation across accounts — sometimes higher, sometimes lower — with no clear explanation provided to shoppers at checkout.
And Instacart has not denied the practice. In a statement included in the full report, the company acknowledged that “some consumers may see slightly higher prices for certain items and lower prices for others; however, most customers see the standard price,” characterizing the practice as part of its pricing tests (2).
Although, initially, Instacart conveyed it had retailer input on pricing, saying, “Retail partners set and control their prices on Instacart and we work closely with them to align online and in-store pricing wherever possible. Instacart is always transparent about pricing.”
However, retailers themselves are sending a different message, aiming to distance their brands from the practice. Target, for example, said it does not control how Instacart sets prices on its platform, according to statements included in the report (3). Instacart “subsequently acknowledged that it scrapes Target’s publicly displayed prices and charges an additional amount to offset its ‘operating and technology costs (3).’”
On its own website, Instacart openly promotes its algorithm-driven pricing technology, mentioning advanced data modeling to optimize pricing and revenue outcomes and that they “create an orthogonal array of data points that changes the game" — language that underscores how sophisticated and opaque these systems have become (4).

Why this matters right now
Dynamic pricing is not new. Airlines, hotels and ticket sellers have relied on it for years. But groceries are different. Food is not discretionary for households and the timing of this shift is especially sensitive.
In an August survey conducted by the Associated Press-NORC Center for Public Affairs Research, 86% of Americans said grocery prices were a source of stress (5), making food costs one of the most widely-felt financial pressures in the country.
Economists say consumers may not realize how common algorithmic pricing has become. According to Newswise (6), Mark Tremblay, an economics professor at the University of Nevada, Las Vegas, has warned that dynamic pricing systems are spreading rapidly across retail categories and could increasingly affect purchases.

When grocery prices fluctuate based on your data profile, rather than supply costs or store location, it raises concerns about fairness and transparency, especially for households already struggling to keep up in today's economy.
What you can do to fight dynamic pricing
In its news release, Consumer Reports argues that pricing practices like these demand greater scrutiny. The organization says consumers and lawmakers may need to push for clearer rules around algorithmic pricing, especially when it affects essential goods like food.
Until then, shoppers aren’t powerless.
While there’s no guaranteed way to avoid dynamic pricing entirely, consumer advocates and tech experts suggest a few practical steps that may reduce your exposure:
- Clear your browser cookies before shopping, which may limit how platforms track your past behavior.
- Use private or incognito browsing modes, which restrict some tracking signals during shopping sessions.
- Compare prices across devices or accounts, especially for larger grocery orders.
- Be cautious with loyalty programs and saved shopping profiles, which may feed additional data into pricing algorithms.
Online forums show that many shoppers are already experimenting with these tactics, sharing anecdotes of price differences disappearing after clearing cookies or switching browsers.
The Consumer Reports findings don’t prove that every shopper is always paying more, but they do show that grocery prices may no longer be as fixed or universal as you might assume.
At a time when most Americans are already stressed about food costs, the idea that neighbors could be paying less for the same groceries adds a new layer of frustration. Until clearer rules emerge, awareness and a few defensive shopping habits may be your best next steps.
