Who this is for
Anyone who has asked an AI chatbot how much an item costs at their local supermarket, pharmacy, or hardware store. The chat cannot see today's shelf tags or weekly circulars.
The emergency brake
- Chat quoted an exact price like “$3.49”? Never rely on it. It may be quoting a 2021 nationwide average or an outdated online blog.
- Need real pricing? Check the grocery store's own app, open their printed weekly circular, or look at the shelf tag in person.
Ask the chat without letting it guess
About 3 min
Open a New chat and give it this exact instruction:
Do not guess today's price. Say you do not know it. Tell me the two things I should read on the shelf tag to compare two sizes. Answer in 2 short lines.
Worked example
A good short response looks like this:
“I don't know today's price at your store.
On the tag, read the total price and the unit price (like price per ounce or per pound) — the lower unit price is the better deal.”
Read the shelf tag in person
About 4 min
Every supermarket and retail store in New Jersey prints two numbers on the small label affixed beneath an item:
- Total item price: What you pay at checkout for this specific container (e.g.
$4.29). - Unit price (often in an orange or yellow box in the corner): What it costs per standard measure — like
$0.26 / ozor$1.89 / lb.
The bulk trap
A big family-size box isn't always cheaper! Sometimes the smaller box on sale has a unit price of 18¢ per ounce, while the giant box is 24¢ per ounce. The unit price tells you the real truth in two seconds.
Complete the weekly proof

You have now finished all core checks for this track. During the upcoming week, complete your single weekly proof:
Weekly proof — When the Chatbot Is the Wrong Tool
Do one of these two real-world actions this week:
- Check one thing the chat told you on the real page before acting, and write down whether the chat matched or the page won.
- OR decide NOT to ask the chat at all because one of the four stop cards applied (health, today's price, legal rule, tax/benefits).
Both count equally as a complete pass. You are in control of the tool.

Success check
- Saw the chat decline guessing real-time prices when instructed
- Can explain where to look for unit price on a physical shelf tag
- Selected one weekly proof action (checked real page OR held back on a stop card)
Common failure modes
| Failure | Fix |
|---|---|
| Asked the chat “Which store in town has eggs cheapest?” | The chat has no live grocery inventory. Check the store's digital circular or look at the shelf. |
| Compared big vs small containers by total sticker price | Look at the unit price (per ounce, quart, or pound) to see which package is truly more affordable. |
