We Had 400 People Shop For Groceries. What We Found Will Shock You.

More Perfect Union | March 20, 2026



EXCLUSIVE: We uncovered a secret corporate scheme to raise grocery prices.

We found that Instacart is using AI algorithms to charge customers different prices for the same items. The scary part? It’s not just online. It’s in physical grocery stores, too.

Our months-long investigation with Consumer Reports and Groundwork Collaborative found it could cost families $1,200/year.

    BREAKING: Instacart is ending all price testing on its platform in the wake of our investigation.

    Reuters reported last week that the FTC initiated an investigation into Instacart, members of the United States Senate have told us they are going to investigate, and numerous state authorities (including in California and Illinois) have reached out to let us know they are going to challenge the company’s practices.

    Since this report was released Instacart's stock price has fallen. Investors in the company became skittish that they were now exposed to greater legal liability.

    Sophisticated embezzlement basically! Like robbing 1 cent from everyone's bank account but personally tailored. Real time Digital ID price tags also need BANNING.

    Wow! This was very eye opening! I had always assumed Instacart's upcharge was due to convenience of the service and that the difference was going directly to them…

    "AI Overview
    Grocery store net profit margins are notoriously thin, typically ranging between 1% and 3%, although they experienced a temporary peak during the COVID-19 pandemic. Margins increased from roughly 2.9% to over 4% during the pandemic due to high demand, but have since fallen back to pre-pandemic levels of 1.6% in 2023."

    I think you guys need to find a different capitalism boogyeman. Grocery stores barely making profits just ain't it.

    Love this! It is refreshing to see something focused on real issues. One thing I’ll point out is they can’t do this to us if we shop in person. Even if you have a loyalty card, you can’t be charged different prices especiallyyyy IF YOU TRACK PRICES AS YOU CHECK OUT. However, since the difference is so small, it makes it easier to overlook. Wow. Definitely won’t be ordering groceries – not that I ever did.

    "Competitive shopping". I had suspected my own PC is cheating me for years. So, every time I shop for airline tickets, I cross checking the air fare prices with my own PC first, then my families PCs (multiple PCs), then my other relatives and friends in different addresses, check prices at different time and dates. Do this yourself and you'll find different prices like I did. I just pick the lowest price, time, date, hotels, rental cars of my travel preferences. If you can beat the system, then GO AROUND the system.

    Seventy five percent of my purchases are BOGO or deep discount sales in bulk and frozen or shelved for later. I only pay full price for weekly items (milk, produce, etc).

    "Judicial Watch"
    just uncovered records showing New York City spent millions of federal taxpayer dollars housing and feeding illegal aliens.

    In hotels.

    With catered food.

    We have the receipts to prove it thanks to 710 pages of records your Judicial Watch received through our Freedom of Information Act (FOIA) lawsuit.

    MPU is a socialist organization aimed at over throwing capitalism. I use it to know which stocks to buy, what industries to invest in. Screw collective organization. If you want to help the poor teach them how to use money.

    What would actually be helpful is to advise consumers on how to beat this system. Does it help to never shop on your phone, only pay cash, wear sunglasses so retailers cant use facial recognition software to figure out who you are in the store, …?

    I'll never shop at a place that has digital tags. Waste of electronics and opens the door waay up to scamming people. Ever Get to check out and find out one of the price tags was off? Imagine if that happened, and when you complained about it the clerks tried gaslighting you into believing that's what the price always had been.
