A shelf card may advertise a multi-buy offer for one package size and dates that do not match the product beside it. GS1 describes trade item identification. Scale lists retail and consumer operating data as an area of interest. GS1 US product identifiers · Scale Data Partnerships
Make two original shelf cards and use dummy packages of similar appearance. Stage an expired card beside the alternate size. Ask the model to read the size and offer dates, and identify what the record establishes about the pictured item. Keep checkout price confirmation separate.
Use a closed shelf set and original labels. Keep shoppers, receipts, checkout screens and live pricing terms out.
Describe a mock convenience shelf sample
Original Fiund exercise
A nearby shelf card needs both the pictured pack size and the offer date
A closed shelf set uses original dummy packages and synthetic promotion cards. There are no shoppers, receipts, actual prices, checkout system or sale.
| Record | Source | What it records |
|---|---|---|
| CSH1 | Card C1 | Original offer lists product P/250 mL, valid days 1–5. Clearly marked multi-buy practice offer; no register record. |
| CSH2 | Shelf image | Day 7 image shows C1 beside P/500 mL. Package size and card validity visible; no 250 mL package in that marked position. |
| CSH3 | Separate card C2 | P/500 mL offer valid days 8–10. Not effective on day 7; no receipt or current checkout confirmation supplied. |
Question for the model
Does C1 support a day-7 offer for the pictured 500 mL item, and does C2 establish a verified checkout price?
Show the reference answer and checks
CSH1 and CSH2 show two mismatches: C1 names the 250 mL variant and expired after day five, while the pictured item is 500 mL on day seven. CSH3 matches size but starts day eight. Neither supports the selected offer at the observed time, and neither provides checkout confirmation. Preserve product identity and date alongside signage rather than infer a live price from shelf proximity or a future card.
- Applying a shelf promotion to a neighboring package of a different size.
- Ignoring an expired or future validity window or treating signage as a verified transaction.
Fields to preserve
- Product and package size
- Defines the eligible variant.
- Card interval and observed date
- Supports the date comparison.
- Signage versus checkout evidence
- Limits the price claim.
Test another case
Move the photo to day 9 but leave C1 visible. Require C2's textual eligibility to be distinguished from what the observed shelf actually displays.
Use original prop labels and synthetic offers. Exclude shoppers, receipts and live terms.
