Seattle City Council votes to ban surveillance pricing in sale of groceries

Original Article ↗ Hacker News Discussion ↗

Seattle has moved to ban “surveillance pricing” in grocery sales, blocking retailers from using individualized data and algorithms to charge different customers different prices for the same items. Commenters weigh the consumer benefits of curbing opaque price discrimination and data exploitation against arguments that such targeting can, in theory, make some goods cheaper for low-income shoppers and is already common in sectors like insurance and air travel. The conversation widens into whether stronger privacy rights — even at the constitutional level — are needed to constrain commercial and government data collection, and how far such rules should extend beyond groceries to other markets.

Scope of the Seattle Ordinance

  • Bill targets “algorithmic-based price discrimination” in retail, with groceries used as a primary example; unclear how far it extends to broader online commerce (e.g., Amazon) or universities/insurance.
  • Loyalty and membership programs are explicitly exempt if discounts are offered on equal terms to all members.
  • Some see it as merely codifying an older “static price” status quo against a new data-driven model.

Dynamic / Surveillance Pricing Concerns

  • Core worry: retailers use detailed personal and behavioral data to tailor prices, charging each person the maximum they’re likely to pay, not just segment-level pricing.
  • Examples cited: different Uber/Lyft quotes on different phones, Amazon showing different prices when logged in vs incognito, travel sites steering certain users to more expensive options.
  • People fear cross-domain uses (e.g., grocery data informing health insurance, or pregnancy/health inferences from shopping patterns).
  • Several argue that opaque, individualized pricing destroys meaningful budgeting and comparison shopping.

Privacy, Data Rights, and Constitutional Arguments

  • Some propose a sweeping constitutional right to privacy that would: ban retention/aggregation of personal data, undercut ad-tech, and constrain government surveillance.
  • Others counter this would be unworkable for schools, healthcare, finance, and research, or would collide with free-speech protections.
  • GDPR is cited as an existence proof that strict consent-based data rules are at least partially workable, though often poorly followed in practice.

Economic and Distributional Debate

  • Classic economic framing: price discrimination lets firms capture more surplus; can sometimes lower prices for low–willingness-to-pay customers while raising them for richer ones.
  • Several argue that in practice firms will simply extract more from everyone they can, not altruistically subsidize the poor; if redistribution is desired, it should be done transparently via taxes and transfers.
  • Airlines and “first class subsidizes economy” are debated; some see it as a rare beneficial case, others say economy essentially pays for the flight.

Enforcement, Scope, and Alternatives

  • Questions about municipal authority and practical enforcement; some expect underfunded, complaint-driven enforcement and private lawsuits.
  • Critics note Seattle is attacking “surveillance pricing” instead of more obvious grocery cost drivers.
  • Alternatives suggested:
    • Mandated real-time price feeds to comparison services.
    • Stronger general privacy laws rather than narrow sector rules.
    • Banning individual-level targeting while allowing content- or cohort-based ads.
