More and more shoppers are concerned about dynamic pricing — people suspect that companies use AI and analyze personal data to charge them higher prices than other customers.

In the US, The Wall Street Journal reported on this “price anxiety” through the example of 38-year-old product manager Nick Nadeau: a hard drive cost him $110 more in the Walmart app than it did his wife. The company attributes such cases to technical errors and insists that prices are in no way linked to customers’ income levels.

Similar complaints are emerging in Russia. Threads users noticed that the price of “Medovichi” on Yandex Lavka varied depending on the account—from 124 to 259 rubles. The service’s press office explained that the base price of an item is always the same within a given dark store, while the final amount takes into account location, operating costs, discounts with the Pay card, and personalized promotions.
