Compare prices across retailers
Build a comparison only after confirming equivalent offers.
01 / INPUTSource records from each retailer
02 / YOUR WORKFLOWMatch variant → align basis → compare
03 / OUTPUTPrice table with match evidence
Keep the right fields.
Workflow field map| Field / step | Input | Rule |
|---|---|---|
| Match | Brand, model and variant | Record ambiguous matches for review. |
| Basis | Pack, condition and currency | Do not mix unit prices and bundle prices. |
| Time | retrieved_at per source | Separate stale observations. |
Before you use the output
Two stores in the sample selector demonstrate different records, not a like-for-like competitor match. Cross-source matching and exchange rates belong in your workflow.
Check one record first.
Start with the smallest useful scope. Compare the returned record with its source, confirm variant identity and inspect missing fields before applying the mapping to a larger dataset.
Keep extraction warnings and the retrieval timestamp with downstream output. When a required field is missing, leave it unresolved or return to the source; do not fill it from an assumption.
