You’re sitting in an airplane seat. You paid $450 for it three weeks ago. The person next to you? They paid $210 because they booked on a Tuesday at 3 AM while wearing wool socks (okay, maybe not the socks, but it feels that way). This is the messy reality of discriminatory pricing. It’s not necessarily about prejudice in the way we usually use that word, though it can be. Mostly, it’s about math. Companies are obsessed with figuring out the "reservation price"—the absolute maximum you are willing to cough up before you walk away.
So, What Is Discriminatory Pricing Anyway?
Basically, it's selling the same product to different people at different prices. No change in the cost of production. No change in the quality of the item. Just a different number on the receipt based on who you are, where you live, or how badly the company thinks you need the item. Economists usually call it price discrimination, but "discriminatory pricing" is the term that makes people’s blood boil when they realize they're the ones paying the premium.
It happens everywhere. Think about senior citizen discounts at the movies. That’s discriminatory pricing. Think about student software licenses or those "first-time user" coupons that make loyal customers feel like suckers. It’s all the same engine under the hood.
The logic is simple: if a business charges one flat price, they lose. Charge too much, and the budget-conscious stay home. Charge too little, and they leave money on the table from the rich folks who would have paid double. By splitting the market, the business wins twice.
The Three "Degrees" of the Game
Economist Arthur Pigou laid this out about a century ago, and honestly, his framework still holds up perfectly in the age of algorithms.
First-degree discrimination is the "Holy Grail." This is where a seller knows exactly what you’ll pay and charges you that specific amount. It’s rare in retail but common in car dealerships or biding on eBay. You’re essentially being squeezed for every penny of your individual "value."
Second-degree is about volume. You see this at Costco. If you buy a 40-pack of toilet paper, the price per roll is lower than if you buy a 4-pack at the corner bodega. The company is discriminating based on the quantity you consume.

Third-degree is the most common. This is where they segment the market into groups. Students, seniors, "early birds," or residents of a specific zip code. If you’ve ever used a VPN to try and get cheaper flights from a "lower-income" country, you were trying to game third-degree discriminatory pricing.
Why It’s Actually Harder to Spot Now
Back in the day, you could see the price on the shelf. Now? The price is a ghost.
Dynamic pricing is the digital-age evolution of this. Uber’s "Surge Pricing" is a classic example. When it’s pouring rain and everyone in Manhattan wants a ride, the price triples. Is that fair? Uber says it’s about supply and demand. Critics say it’s a way to exploit people when they have the least amount of choice.
Then there’s the "Pink Tax." This is a recurring controversy where products marketed toward women—razors, dry cleaning, deodorant—cost more than the functionally identical "male" versions. A 2015 study by the New York City Department of Consumer Affairs found that products for women cost 7% more on average than similar products for men. In the world of discriminatory pricing, gender becomes a demographic shortcut for "willingness to pay."
The Ethics of the "Zip Code" Price
Orbitz once famously got caught showing more expensive hotel options to Mac users than PC users. Why? Their data suggested Mac owners had more disposable income.
Retailers like Staples and Home Depot have been accused of "price steering." If their algorithm detects you are browsing from a wealthy neighborhood, or if you’re physically far away from a competitor’s store, the price on your screen might tick upward. It’s subtle. It’s automated. And honestly, it’s kinda creepy.
Is This Even Legal?
Mostly, yes.
In the United States, the Robinson-Patman Act of 1936 was designed to prevent price discrimination, but it was mainly aimed at protecting small "mom and pop" shops from big chains getting better deals from wholesalers. When it comes to the end consumer, businesses have a lot of leeway.

As long as a company isn't discriminating based on a "protected class"—race, religion, or nationality—they can usually charge what the market will bear. If they charge you more because you’re browsing on a high-end iPhone 15 Pro Max, that’s usually legal. If they charge you more because of your skin color, that’s a massive civil rights violation. The line is often thinner than we’d like to admit, especially when "algorithms" start using proxy data (like zip codes) that correlate with race.
The Psychological Toll
We hate being the "sucker."
There is a concept in behavioral economics called "fairness perception." When Coca-Cola once tested a vending machine that raised prices when the temperature went up, people lost their minds. Technically, it was just supply and demand. Rationally, it made sense. Emotionally? It felt like price gouging.
When people realize discriminatory pricing is happening to them, brand loyalty evaporates. Nobody likes feeling like they're being "profiled" by a database just so a corporation can squeeze an extra $4.00 out of their lunch order.
Why Do We Accept Some Types?
We don't protest when a 6-year-old gets a "kid’s meal" price at a buffet. We don't get mad when a 90-year-old gets a discount on their coffee.

Why? Because we view those as "equitable." We perceive that children and seniors have less "ability to pay." The problem starts when the discrimination feels arbitrary or hidden. If I’m sitting next to you on a flight and I found out you paid half what I did for the same bag of pretzels and 17 inches of legroom, I’m going to be annoyed for the next four hours.
How to Fight Back
You aren't totally helpless. Since the pricing is often based on your digital footprint, you can muddy the waters.
- Clear your cookies. Seriously. Travel sites use them to track how many times you’ve looked at a specific flight. If they see you're desperate, that price isn't going down.
- Use Incognito Mode. It’s not a magic bullet, but it helps prevent some level of price steering.
- Price Match. Many big-box retailers will match their own online price if it’s lower than the in-store price, or vice-versa. They count on you being too lazy to check.
- Abandon your cart. If you’re logged into a site, put items in your cart and then close the tab. Many companies have automated systems that will email you a 10% or 15% discount code 24 hours later to "nudge" you into finishing the purchase. That’s you using their own discriminatory pricing logic against them.
The Future: AI and Personalized Prices
We are moving toward a world where "The Price" no longer exists.
Imagine walking into a grocery store with AR glasses. The price you see on the milk might be $3.50 because the store knows you buy it every week and you’re loyal. The person behind you might see $3.10 because the store is trying to lure them away from a competitor.
This level of hyper-personalization is the endgame for big data. It’s efficient for the business, but it destroys the "common marketplace" where everyone is treated the same.
Actionable Next Steps for Consumers
Don't let the algorithms win. The next time you're making a major purchase—especially for travel, electronics, or insurance—do a "clean room" check. Use a different device or a different browser to see if the price changes.
If you're a business owner, be careful. While discriminatory pricing can spike your margins in the short term, the "unfairness" tax is real. If your customers feel exploited, they won't just leave; they'll tell everyone on social media why they left.
Transparency is usually the better long-term play. If you're going to charge different prices, have a clear, public reason why. "Loyalty rewards" are much easier for people to swallow than "hidden algorithm adjustments."
Stop assuming the price on the screen is "The Price." It’s just the opening offer in a digital negotiation you didn't know you were having. Check other sources, use tools like CamelCamelCamel for Amazon price history, and never buy the first thing you see when you're feeling rushed. Speed is the friend of the price discriminator. Patience is your only real shield.
