Three questions before the comparison.
- Which comparable product options appear in the observed assortment?
- Does the price refer to the same variant, pack and offer terms?
- Which seller, delivery or product details are missing from the comparison?
Illustrative evidence card
An offer to review, not a demand signal
- Marketplace
- Amazon
- Source
- Example public product-offer reference; the actual URL must accompany an observation.
- Observation time
- Illustrative only. Record the actual observation timestamp before using evidence.
- Product match
- Check variant, pack size, seller, currency, delivery and promotion terms. A similar title alone does not establish a match.
- Coverage
- One example offer, not a complete market or catalog. Missing evidence remains unknown.
Observe. Compare. Review.
01 · Observe
Keep the source, time, market and currency with the visible offer. Mark inaccessible or missing fields.
02 · Compare
Check the product match and offer terms before interpreting a difference. An observed price is not a transaction or sales estimate.
03 · Review
A merchant reviews the evidence, coverage and open questions before advancing a range or pricing decision.
Seller economics need a separate, authorized source.
Sales, fees, stock, margin and account-specific terms are private business inputs. This page reads no seller account and supplies no live seller metrics. Agree permission, access and data quality before combining them with public observations.
Start with a question and an accessible catalog.
Market Sense has an existing public-catalog scan and a labeled sample scenario. Readability depends on the source; these marketplace guides do not guarantee direct Amazon or Walmart page scanning. Confirm sources and review criteria for your pilot.
