The everyday version
When they can see you, they can price you
Freezing an account is the dramatic end of that exposure. The everyday end is quieter, and almost nobody notices it: when your financial life is legible — your device, your location, what you’ve bought, what you almost bought — it can be used not to cut you off, but to decide what you pay. This isn’t a forecast. It has been documented for well over a decade.
In 2012, a Wall Street Journal investigation found the travel site Orbitz steering people who browsed on a Mac toward pricier hotels, after discovering that Mac users tended to book higher-end rooms. Orbitz was careful to say it wasn’t charging more for the same room — it was reordering which rooms you saw first. That distinction is the whole game: surveillance rarely has to change the sticker to change the outcome. The same reporting found Staples.com showing an identical stapler at different prices based on a shopper’s estimated location and their distance from a rival store — with the counterintuitive result that people farther from competitors, often in more rural areas, tended to pay more.
Three years later, ProPublica tested the Princeton Review’s ZIP-code-based tutoring prices and found something the model almost certainly never set out to do: customers in heavily Asian-American areas were nearly twice as likely to be quoted the higher price — a gap that held even in lower-income neighborhoods. The company said its prices tracked local market costs, not ethnicity, and that may well be true. That is exactly why it matters: pricing built from data can encode a bias nobody typed in, and you can’t argue with a number you never see.
What began as isolated experiments is now an industry. In a 2025 study, the Federal Trade Commission described a quiet market of middlemen that help retailers set individualized prices from signals as fine-grained as your location, your browsing history, and even your mouse movements on the page — the aim being to estimate what each person will tolerate. The same logic is moving onto store shelves: digital price tags can change a number in seconds, and when lawmakers pressed Kroger on its rollout, they warned the tags could be paired with customer profiles to display each shopper’s “maximum willingness to pay.” Kroger denies using facial recognition or surge pricing, and says the tags mostly speed up markdowns on items near their sell-by date. What isn’t in dispute is the capability — and a 2025 Consumer Reports investigation estimated that one grocery-delivery service’s pricing experiments could cost some shoppers close to $1,200 a year.
This belongs on a page about financial privacy for the same reason the story above does: being seen is being exposed to leverage. A regime uses that leverage to freeze you; a company uses it to price you. Neither works without visibility. And a personalized price is uniquely hard to fight, because it removes the one defense shopping has always had — you can’t comparison-shop a number built for you alone, and you rarely even know it happened.
A caveat, because this subject attracts hype: not every viral clip of two phones showing different prices is surveillance pricing. Plenty of gaps come from ordinary A/B tests, timing, inventory, currency, or a coupon tied to one account — and the cases worth trusting are the documented ones above, not the screenshots. The point isn’t that every price is rigged; it’s that the machinery to tailor a price to you now exists, runs mostly out of sight, and is barely regulated.
For now, the rules are catching up unevenly. The FTC’s study is ongoing, and a federal bill along with measures in more than a dozen states have been introduced to curb surveillance pricing and in-store digital tags — but today little actually stops it, and how exposed you are still comes down to where you live and how much of your financial life is legible in the first place. That thread runs through this whole site.
