Prompt

Act as a careful shopping-research and discount-verification agent.

I am considering buying:

[PRODUCT LINK]

Exact variation:
[SIZE, COLOR, MODEL OR CONFIGURATION]

Quantity:
[QUANTITY]

Shipping destination:
[ZIP CODE OR COUNTRY]

Your goal is to identify the lowest legitimate final cost without changing the product or completing a purchase.

Phase 1: Research

Find current:

- Public promo codes
- Product and storewide sales
- New-customer offers
- Newsletter or SMS discounts
- Free-shipping offers
- Eligibility-based discounts
- Loyalty offers
- Bundles
- Manufacturer rebates
- Cashback
- Competing authorized retailers
- Price-match opportunities
- Open-box or certified-refurbished options
- Relevant recent price history

Prefer retailer-owned pages and recent credible sources.

For every offer, report its source, eligibility, exclusions, minimum spend, expected savings, expiration information and confidence.

Never invent a code.

Phase 2: Verification

If browser access is available, open the cart and test each applicable public code one at a time.

Record:

- Whether it worked
- The discount
- The resulting subtotal
- Shipping or fee changes
- The final displayed total
- Any reason the code failed

Reset the cart between tests.

Phase 3: Optimization

Determine:

- The best single offer
- The best stackable combination
- The lowest immediate checkout price
- Any delayed cashback or rebate
- Whether a code invalidates cashback
- Whether another legitimate retailer is cheaper
- Whether price matching is available
- Whether waiting for a predictable sale is financially reasonable

Hard restrictions:

- Do not change the product or quantity
- Do not create an account without approval
- Do not join a paid membership
- Do not start a subscription
- Do not enter payment information
- Do not place the order
- Stop before the final purchase step
- Pause for logins, CAPTCHA checks or sensitive information
- Ask for approval before taking any action with a recurring or financial commitment

Finish with a clear recommendation showing the lowest verified cost, the steps required to get it and anything I should personally confirm.

The Ruthless Buyer Prompt

When you use this prompt, Gemini enters "Deep Think" mode (if available) to: Cross-reference the current price against 24-month historical lows. Identify "fake sales" (where the price was raised just to be discounted). Scan for identical "white label" products (same item, different brand name, half the price).

ChatGPT Flight Deal Architect.

Airlines price flights like a casino, not a menu. They use inventory buckets, married segments, point-of-sale tricks, and demand forecasting that punishes inflexible shoppers. ChatGPT is the weapon because it expands your options while staying logical. You can now pull live prices directly inside ChatGPT using the Expedia or Booking.com apps, or use web search with citations.
