Is this actually a good deal?

A big percentage on a sale sticker doesn't always mean a big saving. Fill in what you're looking at, then hand the prompt to your AI assistant - it will check the real price history and give you a verdict.

What are you looking at?

All four are optional. Leave a field blank and your assistant will ask for it.

Your prompt

1,976 characters
I want you to check whether this advertised deal is genuinely good value or whether the discount is mostly marketing.

PRODUCT: [product name]
URL: [paste product URL]
CURRENT PRICE: [price]
ADVERTISED WAS/RRP PRICE: [price, if shown]

I'm in South Africa - work in Rands (R) and check South African retailers.

Please research the exact same product/model and:
Check the current price and, if possible, the manufacturer's and other major retailers' prices.
Look for actual selling prices for the last 12 months, using price trackers, previous promotions, archived pages, retailer emails/deal sites and other reliable sources.
Use prices from 12-24 months ago only as secondary context. Do not use prices older than 24 months to assess whether today's deal is good.
Work out the recent normal/typical selling price, lowest reliable recent price, and today's price. Do not assume the retailer's RRP or "was" price is the normal price.
Check whether the price was increased shortly before the promotion.
Consider inflation, exchange rates, product changes and other factors when looking at older prices. Do not let an unusually low old price distort the assessment.
Check whether the same product is currently cheaper elsewhere.
Calculate the advertised discount AND the actual saving compared with the recent normal selling price.

Give me this summary:
Today's price:
Advertised saving:
Recent typical price:
Lowest reliable price in last 12 months:
Best current price elsewhere:
Actual saving vs typical price:

VERDICT:
🟢 GOOD DEAL — meaningfully cheaper than its recent normal price.
🟡 FAIR DEAL — some saving, but not exceptional.
🔴 NOT A REAL DEAL — normal price dressed up as a promotion or misleading reference price.
⚪ INSUFFICIENT EVIDENCE — not enough reliable recent data.

Briefly explain your verdict and link to the strongest evidence. Clearly distinguish between verified prices and retailer claims. Do not guess where reliable price history cannot be found.
Open in ChatGPT Open in Claude Open in Gemini

Gemini can't carry the prompt in a link, so tapping it copies the prompt for you to paste.

Ask it to show its working

A good answer names its sources and separates verified prices from what the retailer claims. If it can't find real price history, it should say so rather than guess.

Keep it as a reusable skill

If you'd rather not come back to this page every time, save the prompt once and reuse it all season.

  • Claude - create a Project and paste the prompt into the project instructions, then just name a product each time.
  • ChatGPT - create a Custom GPT (or a Project) and paste the prompt as its instructions.
  • Gemini - create a Gem and paste the prompt into its instructions.

Nothing you type on this page is sent to MyBento. The prompt is assembled in your browser and only goes where you send it.
