A price shown by an AI shopping assistant does not, by itself, tell you whether it was personalized. The assistant may be relaying a retailer’s public listing, showing an account-specific promotion, applying location or delivery context, or displaying an offer that is no longer current. To investigate a difference, match the product, seller, time, location, delivery terms, account status, and promotion eligibility—and compare the assistant’s source with the retailer’s listing and checkout total. Even a repeated difference is a clue, not proof that personal data set the price.
What counts as personalized pricing?
Personalized pricing uses personal data, or an inference about a person’s willingness to pay, to set that person’s price or effective price. An effective price can differ because of a targeted coupon even when the listed price is the same. The Federal Trade Commission described this definition in an August 2026 proposed enforcement policy statement; it is a proposal, not a finding that every retailer or shopping assistant personalizes prices.

Other causes of price differences are not the same thing. Dynamic pricing changes with conditions such as demand or inventory; regional offers may reflect local market conditions; and a discount may be limited to reward-program members. These categories can overlap, so two different prices do not reveal which explanation applies. The FTC says demand- or inventory-based dynamic pricing is permitted under its fees rule when pricing information is not misleading. FTC fees-rule FAQ

How can I tell whether an AI shopping assistant is showing me personalized prices?
Start by identifying exactly what the assistant is showing: a retailer’s listed price, a promotion or coupon, an estimate, or a checkout total. Then check where the figure came from. Save the assistant’s cited link and compare it with the retailer’s own product page and final checkout price. If the assistant does not identify the source or explain the offer conditions, its response alone cannot verify whether the price is current or personalized.

Use this checklist to make a fair comparison:
- Match the item and seller. Confirm the exact model, variant, size or color, condition, and seller. A similar product or a different marketplace seller is not a like-for-like comparison.
- Record the time. Note the date and time for each check. Demand, inventory, and time can change an offer.
- Match location and delivery. Use the same region or delivery address and shipping option. Record whether the displayed amount includes shipping and mandatory charges. Under the FTC’s fees FAQ, covered offers must prominently show the total price; shipping may be excluded from the initial price but must be disclosed before payment.
- Record account and offer eligibility. Note whether each session is logged in, whether a loyalty membership applies, and whether a coupon or promotion is available to everyone or only eligible customers. A member discount is not the same as an offer open to all shoppers.
- Compare through checkout. Check the retailer’s listing and the final checkout total, and preserve the source link or screenshots. Note any stated expiration, conditions, or claim that the offer is personalized.
- Repeat under matched conditions. Recheck the comparison rather than drawing a conclusion from one pair of prices. A difference establishes that the offers differed; it does not establish why.
This is a practical way to rule out common differences, not a validated forensic test for identifying the algorithm or data behind a price.
What can explain a price difference besides personalization?
Before attributing a gap to personal data, check whether one of these factors changed:
- Demand or inventory: A retailer may adjust prices as demand or available stock changes.
- Timing: The assistant may have retrieved an older listing, or the offer may have changed between checks.
- Seller or product variant: Marketplace sellers, models, sizes, colors, and conditions can carry different prices.
- Location and delivery: Local availability, shipping method, and delivery region can affect the offer or its total.
- Account or promotion eligibility: A member price, coupon, or targeted promotion can change the effective price without changing the public list price.
In its 2025 report on algorithmic pricing in G7 jurisdictions, the OECD summarized an Italian Competition Authority preliminary review of airline prices. In that specific review, personalization based on browsing history, location, or device type was rare, while most price differences were linked to booking time and demand. That airline finding should not be generalized to other retailers or AI shopping assistants. OECD report

What evidence exists that personal data can affect prices or offers?
In January 2025, FTC staff reported initial findings from documents obtained from intermediary firms. The FTC said the firms it examined worked with at least 250 clients selling goods or services, including groceries and apparel, and described possible uses of location, demographics, browsing and shopping history, mouse movements, and abandoned-cart behavior to tailor prices or promotions. The announcement included hypothetical examples to protect confidential information and said the study was ongoing. It is evidence that these tools and data uses appeared in the material staff reviewed—not proof that a particular retailer or assistant personalized your price, or that personalized prices are widespread across shopping assistants. FTC study announcement
FTC staff also said more research was needed to understand when surveillance pricing raises consumer prices and how it affects information asymmetries. Personalization does not necessarily mean a higher price: a targeted coupon may lower someone’s effective price, and seeing a coupon does not prove another shopper paid more. FTC issue spotlight

A clear notice or offer condition can help identify a personalized price or promotion, but the absence of one does not prove the price was not personalized. An OECD lab experiment involving consumers in Ireland and Chile found that online disclosures had only limited effects on people’s ability to identify and understand personalized pricing. The study did not confirm a significant effect on purchasing behavior. OECD study

Policy status also matters. The FTC’s August 2026 announcement concerned a proposed enforcement policy statement, with comments due September 18, 2026. The announcement said the agency viewed undisclosed collection or use of personal data to set a price as potentially violating laws it enforces. That describes the proposal’s position, not a final rule or a general ban on personalized pricing. FTC announcement
What to do if the difference persists
- Keep the evidence together. Save dated screenshots, the assistant’s source link, the retailer’s listing, and the checkout total, including the offer terms and account state.
- Ask what the assistant is reporting. Look for whether it labels the amount as a listed price, member offer, coupon, estimate, or final total. If the source or conditions are missing, treat the figure as unverified.
- Check the retailer’s own explanation. Compare the offer and eligibility terms on the retailer’s site rather than assuming the assistant has access to the same current information.
- Describe the result narrowly. You can say that matched checks showed different offers. Without evidence about the retailer’s methods, do not claim that a particular personal signal or algorithm caused the difference.
Private browsing or a VPN might change some signals, but neither is established as a reliable way to change a particular price. A changed price after switching sessions would still need the same checks for time, location, seller, delivery, and offer eligibility.
