title
An ordinance relating to prohibiting algorithmic-based price discrimination; requiring covered retailer disclosures to consumers; requiring that covered retailers retain certain records; and adding a new Chapter 7.35 to the Seattle Municipal Code.
body
Recitals:
Many jurisdictions across the country, including California, Connecticut, Colorado, Illinois, Maryland, New York State, and New York City, among others, have considered, are considering, or have passed legislation to regulate the use of algorithmic software and consumer data to set prices.
The Washington State Legislature considered regulating algorithmic price discrimination in House Bill 2481 in the 2026 legislative session.
In January 2025, the Federal Trade Commission released a report detailing methods of algorithmic price setting. The report found that algorithmic price discrimination tools are being developed and marketed across “[s]everal types of consumer-facing businesses . . . including grocery stores, apparel retailers, health and beauty retailers, home goods and furnishing stores, convenience stores, building and hardware stores, and general merchandise retailers such as department or discount stores.”
The report further found that “[c]onsumer segmentation and profiling tools create unique consumer profiles and divide consumers into segments based on attributes or behaviors that are either inferred or explicitly defined. Those segments can then be used as targets for ads, promotions, and coupons based on what a company has learned about a consumer, including how the consumer interacts with its website, what they have spent on specific products or services, or predictions about what that consumer might purchase in the future.”
These tools create the environment for retailers to set individual prices through both different base prices, but also “discounts” that result in higher prices for some consumers, based on their inferred willingness to pay. This is often accomplished through what is called “false reference pricing,”-the practice of advertising a false “original price” to make discounts appear larger than they are. “Companies that collect or obtain individualized information about their actual or potential customers can potentially use a variety of features to target prices to specific consumers and charge particular groups higher prices or use those features to generate greater profits.”
These practices are being used by grocers, delivery service providers, and mixed-use stores today.
According to a Consumer Reports investigation Kroger grocery stores collect extensive consumer data, use it to make detailed inferences about consumers, including an “income predictor”, determine loyalty levels, and target discounts to consumers based on those inferences. A “shopper deemed to have less education or with a lower income, for example, could end up getting fewer of Kroger’s best discounts.”
Consumer loyalty and frequent shopper cards are widely adopted and provide a mechanism for retailers to track consumer purchase history and target discounts accordingly. 95 percent of Kroger transactions are tied to a loyalty card. In 2023, Kroger’s marketing materials claimed that it had “unaggregated” data about individual product sales “from 2 billion annual transactions across 60 million households [that it could tie to individuals] with a persistent household identifier.” The materials state “[w]e have collected over 2,000 variables on customers.”
Retailers’ own data is combined with data purchased from third-party data brokers, including “demographic and financial data, such as income levels, debt, or even how often someone shops online. Together, these data form a comprehensive picture of an individual’s behavior, preferences, and financial situation.”
This level of data allows companies to determine “purchasing habits, urgency of need, and geographic constraints and adjust prices accordingly.” This allows companies “to identify an individual’s “pain point”-the maximum price a consumer will pay” by “experimenting with higher and higher prices for individuals who may be more financially desperate.”
Frequently, algorithmically generated prices as well as discounts become not a means for a better deal for consumers, but a method to identify that “pain point”. Instacart offers pricing software to grocers with the capability for grocers to provide individualized prices, promotions, and discounts. “Instacart claims the technology can increase grocery store sales by 1 to 3 percent and ‘incremental margins’-the extra profit a company gets from each additional sale-by 2 to 5 percent.”
In 2025, Consumer Reports conducted an experiment with 437 shoppers adding identical items to their Instacart shopping carts and comparing prices. About 75 percent of the products were “offered at different prices to different customers. Some products were offered at as many as five different prices, and price variations for the same products ranged from as little as 7 cents to $2.56 per item” and between $114 and $123 in total for all items.” “Based on how much Instacart says the typical household of four spends on groceries, the average price variations observed could translate into a cost swing of about $1,200 per year.”
The investigation further found that Instacart offered different “original” or “reference” prices to different consumers, thus making purported discounts seem larger or smaller. The investigation includes Seattle-specific findings: participants shopping on Instacart at a Seattle Safeway were shown different “reference” or prices for saltine crackers ranging from $5.93 to $6.69.
A 2026 poll conducted by Groundwork Collaborative and Data for Progress found “80% of voters agree that every customer should pay the same price for the same item”, that 76 percent of American support efforts to end algorithmic pricing schemes and that 72 percent would accept smaller discounts in exchange for all consumers being offered the same price. A nationally representative survey conducted by Consumer Reports in September 2025 found that 72 percent of respondents did not want Instacart to charge different consumers different prices for any reason. Therefore,
Be it ordained by The City of Seattle as follows:
Section 1. A new Chapter 7.35 is added to the Seattle Municipal Code as follows:
Chapter 7.35 Fair Pricing and Transparency
7.35.000 Findings
A. In the exercise of The City of Seattle’s (City’s) police powers, the City is granted authority to pass regulations designed to protect and promote public health, safety, and welfare.
B. This ordinance protects and promotes public health, safety, and welfare by protecting consumers, ensuring equitable and fair pricing of grocery goods, prohibiting algorithmic-based price discrimination, and addressing factors that artificially inflate or modify consumer prices for groceries and other essential goods based on personal information.
C. The use of algorithms for algorithmic-based price discrimination threatens fair market access to grocery goods. The use of automation and algorithmic pricing models in retail grocery sales exacerbates inequality and undermines consumer trust. The price of retail grocery goods should be rooted in fairness, not in profiling or prediction.
D. Comprehensive consumer protection is needed to prevent discriminatory and opaque pricing practices in retail grocery sales as businesses increasingly adopt data-driven technologies to set prices. Innovation should not come at the expense of transparency, fairness, or access to grocery goods.
E. Prohibiting the use of electronic shelf label systems for algorithmic-based price discrimination by covered retailers will protect consumers from data collection without their knowledge from their electronic devices, such as smartphones, to modify the price of grocery goods for individual shoppers. Pricing should remain consistent and be clearly posted.
F. The prohibition of algorithmic-based price discrimination will protect consumers from profiling and ensure equitable and fair pricing of grocery goods.
