Good point. Charging people different prices online is also logistically difficult, which also makes me think this is rare.

Oddly, this is doing numbers. 2 clarifications:
1) Charging different prices to different segments is pretty accepted in cases like senior discounts (ie, poor people pay less).
2) IMHO, true “surveillance pricing” is rare because it really pisses people off & firms faced PR blowback for trying this.

Respectfully, charging different prices to different groups of consumers usually means that poorer people pay less. A classic example would be seniors discounts.

IMHO, true “surveillance pricing” is rare because it really pisses people off & firms faced PR blowback for trying this.

Different customers, different prices: Companies use data for personalized pricing Between surveillance pricing and discounting, it's harder than ever to figure out if you're getting the best price.

Imagine a group of 5-year-olds playing a board game. The rules are clear, the goal is fair, and one child edges ahead — until, suddenly, another child starts losing. That’s when the trouble begins. “He cheated!” the losing child yells. “I’m the winner anyway!” he declares. And then, like clockwork, he flips the board. In the world of kindergarten conflict resolution, we expect this kind of behavior. We chalk it up to development. We teach better sportsmanship. What do we do when the president of the United States behaves this way? On Friday, President Trump fired the head of the Bureau of Labor Statistics — the nation’s workaday scorekeeper of employment, wages and productivity. Why? Because the data didn’t make Mr. Trump look good. The statistics were inconvenient. So the president didn’t just challenge the findings; he fired the statistician. That’s not governing. That’s board flipping.

Janet Yellen's husband & Econ Nobel Laureate George Akerlof:

"...when presidents flip the board, it’s not just a game that ends. It’s the pieces of democracy that get scattered to the floor."
