“Is This Actually a Good Deal” Fact-Check Prompt

Lifestyle Updated August 26, 2026 by GenPrompto
Prompt
I'm looking at [product] listed at [current sale price], claimed to be [X]% off a [original price] list price. Based on typical pricing for this product over the past several months, does this look like a genuine discount, or does the list price look inflated to make the discount appear larger than it is? What would you consider a genuinely good price for this specific product?

What this does

Fact-checks a specific advertised discount against typical pricing, rather than taking a "X% off" claim at face value.

Variations

One more version, ready to copy on its own.

Category-Wide Version
For [product category, e.g. “wireless earbuds”], what is a realistic price range I should expect to see during genuine Black Friday/Cyber Monday sales, versus what retailers might list as an inflated “original” price to make a smaller discount look bigger?

Who this is for

Anyone who wants to verify a specific Black Friday or Cyber Monday deal is real before buying, not just trust the advertised discount percentage.

Example Output

“Based on this product's typical pricing over the past six months, the $80 "original" price appears inflated — it has regularly sold for $55-60. The current $45 sale price is a genuine discount from typical pricing, but the advertised "44% off" overstates the actual savings versus what you'd normally pay.”

This works especially well combined with a separate price-history tool or browser extension — use this prompt for the reasoning and context, and a dedicated price-tracking tool for hard historical data when it matters for an expensive purchase.

Tips for better results

  • Include the exact current price and the claimed original price — specific numbers get a much more useful answer than "is this a good deal."
  • If the model doesn't have reliable pricing history for the specific product, ask it to reason from the category's typical pricing pattern instead as a rough check.
  • This works best for well-known products with established pricing history — a brand-new release has no meaningful "typical price" to compare against yet.

What didn’t work as well

Asking generically "is this a good deal" without specific prices produced a vague, unhelpful answer that couldn't actually assess anything — including the exact current and claimed-original prices let the model reason about the specific numbers.

FAQ

What if the AI doesn’t have specific pricing history for my product?

Ask it to reason from typical pricing patterns for that product category instead — less precise, but still a useful sanity check.

Should I trust this over a dedicated price-tracking tool?

For anything expensive, use both — this prompt is good for reasoning and context, a dedicated price-history tool gives harder historical data.

Does this work for deals other than Black Friday, like everyday “sale” pricing?

Yes — the same fact-checking approach applies to any advertised discount, any time of year.
