You have found something you want to buy. Before opening several coupon sites, you ask your AI assistant whether the store has a discount code. What should you trust in its answer?
Look for a published offer and its conditions. A familiar-looking code such as WELCOME10 is only a string until there is a source for it. Even a genuine offer may exclude your product, country or order.
Here is a way to use ChatGPT or Claude to investigate a discount without turning a suggestion into a promise.
Start with the product and the store
Give your assistant the product link, the version you want and the country where you will order. Add whether you are a new customer if that affects eligibility. You do not need to share payment details.
Try this prompt:
Check this product at this store: [link]. I am ordering in [country]. Look for a published discount code and link to its source. Show the conditions, expiry if stated, and whether it applies to this product. Do not guess a code. If eligibility is unclear, say what I need to check.
This separates three questions that often get blurred together: does a code exist, could your order qualify, and does the checkout accept it?
Ask where each code came from
A useful answer gives you somewhere to check. That might be the store's promotion page, an offer supplied through a shopping connector, or another named source. Open the source and read the offer before relying on it.
Pay particular attention to:
- Minimum spend and excluded products or brands.
- First-order, membership or subscription requirements.
- Country, currency and delivery restrictions.
- The expiry date and any limit on combining offers.
An offer marked “up to 20%” does not mean 20% off every item. A delivery promotion may also save more than a product code on a small order. Ask your assistant to explain the actual condition rather than repeat the headline.
Use Passt inside ChatGPT or Claude
Passt connects your assistant to a catalog of online stores and products. Where the catalog supplies a store's published discount information, your assistant can include it with the result. Passt is free to use and does not require a separate Passt account; you still need access to your chosen assistant.
Add it from the Passt install section, then select GenesisPay Catalog, the directory name used for Passt. Ask:
Use GenesisPay Catalog to find wool runners under $120. Include any published discount information in the results, its conditions and the source. If a result has no discount information, say that the result does not include a code. Do not infer that the store has no other offers.
Catalog coverage is limited to the stores and products it reads. A search without a code is still useful: you can compare the listed product, check the store's own promotions or decide the full price is acceptable.
Passt reads catalog information. It does not place an order, apply a coupon to your cart or test whether a checkout accepts it. Some results contain marked affiliate links, from which GenesisPay may earn a commission.
A real catalog example
On 4 November 2026, we searched Passt's catalog for wool runners and requested three results. The catalog returned these Allbirds listings:
| Product | Listed price in the response | Discount information in that result |
|---|---|---|
| Women's SuperLight Wool Runners, Natural Black with Light Grey Sole | $120 USD | None supplied |
| Women's SuperLight Wool Runners, Natural Black with Blizzard Sole | $120 USD | None supplied |
| Women's Wool Runner-up Mizzles, Natural Grey | $60 USD | None supplied |
Those are catalog observations from that date, not today's checkout prices. We did not test a coupon or make a purchase. The search illustrates why the response matters more than an expectation of a discount: it provided product information but no code in those three results. It did not establish whether Allbirds had other promotions.
The two $120 products also would not meet a strict under $120 budget. Ask the assistant to apply your budget to the actual listed prices rather than quietly change it to “$120 or less.”
Confirm the price at checkout
Open the store's own product page and check the size, color, quantity and availability. Enter an eligible published code at checkout, then read the total before paying.
Compare the amount after the discount with shipping, tax and any subscription commitment included. A lower product price can become a higher order total once delivery is added.
Keep the store's confirmation for the order you actually place. An assistant's earlier answer is not an order confirmation.
When the code does not work
Check the stated conditions first. Your cart may be below the minimum, the item may be excluded, or the offer may have ended. If the reason remains unclear, ask the store rather than asking an AI to generate variations of the code.
You can also ask the assistant to find a different retailer or a similar product within your budget. Give it the same requirements so that a cheaper alternative does not quietly change the size, material or model you wanted.
What makes a useful AI coupon finder
Choose a tool that identifies its sources, keeps eligibility conditions visible and can return “no code in these results.” Treat a checkout-tested code, a published code and an unsourced suggestion as different things.
For shopping in an existing conversation, add Passt to ChatGPT or Claude. Ask for the product first, then for the published discount information available with it. You choose what to buy and pay at the store.
