If an AI chatbot shows you a different price or promotion from the one shown to someone else, do not assume the chatbot—or the seller—has illegally discriminated. First make the offers directly comparable, save dated proof, and ask the seller in writing what caused the difference. Timing, inventory, location, sales channel, account status, promotion eligibility, delivery terms, or personal-data-based pricing can all produce different totals.
A chatbot may simply be displaying an offer generated by a retailer or booking intermediary. The fact that two conversations produced different answers does not, by itself, prove that the chatbot set the price, that personal data caused the difference, or that a law was broken.
Start with the fastest, safest response
- Match the conditions. Check the exact item or service, seller, quantity, currency, destination, date and time, account or loyalty status, promotion eligibility, delivery terms, taxes, fees and checkout stage.
- Save evidence. Keep dated screenshots or saved pages of both chatbot conversations, the displayed prices, the final checkout totals, product details, offer terms and the exact prompts and replies.
- Ask the seller for a written explanation. Ask whether the difference reflects timing, inventory, location, channel, promotion or loyalty eligibility, or personal-data profiling, and request the total price that applies to you.
- Escalate only when appropriate. Use a consumer-protection authority or consumer association if the seller will not explain a potentially misleading practice. The correct agency depends on your country and the type of conduct.
Keep your wording factual. Say that two users received different offers under apparently similar conditions; do not state as fact that the chatbot used your personal data or that the retailer charged you more because of your identity unless reliable evidence supports that conclusion.
Why two users can receive different offers
Time, demand and inventory
Prices can change between two chats because the seller has updated inventory, demand, exchange rates, a scheduled sale or an expiration time. The Federal Trade Commission (FTC) says businesses may use dynamic pricing based on demand or inventory when the pricing information is not misleading. A friend’s screenshot from yesterday is therefore not necessarily a promise that the same price is available today.
#1 Best Overall
Location and delivery destination
Country, state, postal code, store location and delivery destination can alter taxes, shipping, local availability and regulatory charges. Entering a destination late in checkout can make an initially displayed price look different from the final total. Under European Union guidance, objective differences such as delivery costs can justify different totals, while a trader cannot charge an EU national more solely because of nationality or country of residence.
Account, loyalty and promotion eligibility
A logged-in customer may see a member price, a first-order code, a student or business rate, a targeted coupon or a promotion limited by region or account history. Check whether both users were signed in, had the same membership tier and used the same code. A promotion that is unavailable to everyone should not be presented in a way that makes the generally available total appear lower than the price offered to everyone, according to the FTC’s fees guidance.
Sales channel and checkout stage
A seller’s website, mobile app, marketplace listing, telephone channel and chatbot may expose different inventory or fee rules. A conversational quote may exclude taxes, delivery, service charges or required add-ons until checkout. Compare the complete amount payable, not only the first number in a chat response.
Personalised pricing and profiling
Personalised pricing means using information about an individual to set a price based on what a company believes that person is willing to pay. The FTC has identified possible inputs such as precise location, browsing history, demographics, mouse movements and products left in an online cart. These examples came from staff work and hypothetical scenarios; they do not prove that a particular retailer used any one input against you.
The FTC released an August 2026 statement on personalised pricing as a draft for public comment. It says the agency does not have authority to ban personalised pricing in every circumstance, while warning that failing to disclose the use of personal data may violate laws the agency enforces. Treat the statement as a proposal, not a final rule or a blanket prohibition.
The chatbot may be the messenger, not the pricing engine
A chatbot can retrieve a seller’s current catalogue, apply a promotion, or relay a human-configured policy. Two transcripts therefore show what each user was told, but not necessarily which internal system calculated the amount. Ask the seller which system supplied the quote and whether the chatbot can honour it. Do not infer causation from the interface alone.
Step 1: prove that the offers are comparable
Before accusing a seller of unfair treatment, build a side-by-side record. Use the same product page or service description where possible and capture the entire checkout path.
| Comparison point | What to match | Why it can change the result |
|---|---|---|
| Item or service | Model, size, term, package, seat count, dates and quantity | A small specification change can create a different base price. |
| Seller and channel | Same legal seller and the same website, app, marketplace or chatbot | Channels may use separate inventory, commissions or promotions. |
| Time | Date, time zone and whether a sale or quote had expired | Demand, inventory and scheduled campaigns change over time. |
| Location | Country, state or province, postal code, store and delivery destination | Taxes, shipping, availability and local rules vary by destination. |
| Account status | Guest or logged-in state, loyalty tier, subscription and order history | Member and targeted rates may require eligibility. |
| Promotion | Code, referral, first-order condition, minimum spend and expiry | A discount may apply to one account or only under stated conditions. |
| Currency and payment | Displayed currency, conversion method and payment-related charges | Conversion and payment fees can alter the total. |
| Delivery and fees | Shipping speed, handling, service fees, taxes and optional add-ons | The headline price may omit costs added at checkout. |
| Checkout stage | Initial quote, cart, payment page or final confirmation | Later stages often reveal mandatory charges or eligibility checks. |
If any row differs, record that difference rather than calling the offers identical. Matching every row still does not establish the cause; it only removes obvious explanations and gives the seller a useful question to answer.
Step 2: preserve a dated evidence trail
Capture the conversation itself
Save screenshots or exports showing the chatbot name, date, time zone, prompts, replies, displayed currency and any link or product identifier. Keep the full exchange, not only the sentence containing the price. A prompt such as What is the total price for two seats delivered to [destination] today? is more useful when the exact destination, date and account state are also recorded outside the prompt.
Capture the seller’s terms and final total
Save the product or service description, promotion terms, expiration time, shipping method, taxes, mandatory fees and the final checkout total. If the price changes when you sign in, enter a postal code or reach payment, save each stage. Preserve the currency and the page address exactly as displayed.
Rank #3
Record account and privacy context
Note whether you were logged in, using a loyalty account, browsing in a particular region, returning from an abandoned cart or using a device associated with prior purchases. The FTC’s January 2025 initial staff perspective lists location, browsing patterns, demographics, mouse movements and abandoned-cart behaviour as possible inputs examined in personalised-pricing systems. That list is not proof that a specific seller used those inputs, but it explains why context and timing matter when you document a discrepancy.

Store unedited screenshots and downloaded pages with filenames that include the date and time. If a friend provides evidence, ask for the original capture and the conditions under which it was obtained. Do not alter an image to highlight a number without retaining the original version.
Step 3: ask the seller a precise written question
Contact customer support, the merchant named in the checkout, or the service provider that issued the quote. Include the two conditions without publishing unnecessary personal information. Request a written reply and ask for the amount the seller will actually charge.
A useful message is:
“On 16 October 2026 at approximately 14:00 UTC, your chatbot quoted [item or service] at [amount and currency] for [conditions]. A second user received [other amount] under these conditions: [list only material differences]. Please confirm the applicable total price and explain whether the difference is due to timing, inventory, location, sales channel, promotion or loyalty eligibility, delivery terms, or personal-data-based profiling. If an automated system or profiling was used to personalise the price, please identify what disclosure applies before purchase.”
Ask whether the quote is guaranteed, how long it remains valid, and whether the chatbot is authorised to issue it. A seller may explain that one offer expired, required a code, excluded delivery or came from a different channel. Keep the response with your evidence.

Step 4: decide whether to escalate
When the explanation resolves the issue
If the seller identifies a genuine difference—such as a different destination, expired promotion, inventory change or member eligibility—save the explanation and decide whether to proceed. You can still ask for a correction if the advertised total was misleading or mandatory fees appeared only at the end.
United States considerations
The FTC’s fees FAQ allows dynamic pricing based on demand or inventory when the information is not misleading. It also addresses promotions that are unavailable to everyone: they should not be used to make the generally displayed total appear lower than the total offered to everyone. For interactive online disclosures under that rule, required information must be unavoidable and written in plain language.
The FTC’s August 2026 personalised-pricing statement is a draft for public comment. Its status after the comment period is not established here, so do not describe it as a final rule. If your concern is deceptive fees or a misleading price presentation, consult the FTC’s current reporting and fees guidance. A mere difference between two prices is not automatically an FTC violation.
European Union considerations
The European Commission’s Your Europe guidance says personalised pricing is not itself illegal under the EU rules summarized there. Consumers must be told before purchase when a price is personalised through automated decision-making and profiling of their consumer behaviour. The guidance also explains that traders cannot charge an EU national more solely because of nationality or country of residence, while objective differences such as delivery costs may justify different totals.

The Commission’s Price Indication Directive guidance requires selling and unit prices to be unambiguous, easily identifiable and clearly legible, and sets rules for genuine price reductions and prior prices. If the seller will not clarify a potentially misleading display, contact your national consumer association or the European Consumer Centres network for cross-border help.
Other countries and states
Rules vary by jurisdiction, product and sector. Check the consumer-protection authority where you live and the law governing the transaction. Keep your complaint narrow: identify the seller, the dates, the matched conditions, the amounts, the disclosure shown and the remedy you want. Do not claim that a specific legal violation occurred unless the authority or a qualified adviser has assessed it.

A 2024 European Commission report described a small-scale test in which prices differed for 6% of 207 products. The Commission expressly cautioned that the test cannot support general conclusions about how common personalisation is or how it affects consumers. It is not a probability that your chatbot will show a different price.
An FTC January 2025 release said the intermediaries examined worked with at least 250 clients selling goods or services, including groceries and apparel. That is a count of clients of the intermediaries reviewed, not a count of retailers proven to use every form of personalised pricing.

No broadly representative statistic in these materials measures how often AI chatbots themselves give different users different prices. The evidence concerns pricing practices by sellers and intermediaries generally, so a transcript alone cannot establish that an AI model made the pricing decision.
Common mistakes and how to avoid them
- Comparing screenshots without conditions: Record destination, account, time, quantity, currency and checkout stage.
- Confusing a discount with the base price: Check eligibility, minimum spend, expiry and whether delivery or fees were excluded.
- Assuming the chatbot is the seller: Identify the merchant or intermediary named in the offer and direct the complaint there first.
- Deleting the original chat: Export or screenshot the complete exchange before refreshing or signing out.
- Using a regulator as a price-matching service: Authorities investigate possible violations; they do not guarantee that a seller will honour a cheaper quote.
- Overstating what personalisation proves: Possible inputs listed by regulators are not evidence that your data caused a particular price.
- Posting personal data publicly: Redact account numbers, addresses, payment details and private chat content when sharing evidence.
A practical decision checklist
- Do both offers identify the same item or service, seller, quantity and term?
- Were the date, time zone, currency, destination and delivery method identical?
- Were both users at the same checkout stage, with the same taxes and mandatory fees included?
- Were both accounts equally eligible for the promotion or loyalty rate?
- Have you saved the exact prompts, replies, terms and final totals with timestamps?
- Have you asked the seller, in writing, what caused the difference and what total applies?
- Does the response explain the difference, or does it leave a potentially misleading disclosure unresolved?
- Which authority or consumer association covers the transaction’s jurisdiction and issue?
Use the checklist to separate an ordinary change in offer conditions from a pricing practice that deserves further scrutiny. Matching conditions, preserving evidence and obtaining a written explanation gives you the strongest basis for deciding what to do next.
