What you can answer with it
- Is my product cheaper on one app than another?Each day shows the lowest and highest price and where each was seen.
- Is a seller breaking my minimum price?A wide gap on a day points to the listing priced below the rest.
- Do prices differ by pin code on the same app?Prices are kept per pin code, so the gap includes differences within one app.

Method and limits
Rewalto matches the same product across retailers and keeps each listing's daily price readings. A day shows a gap only when two or more matched listings were priced that day. Matches come from an automated matcher whose precision is measured on a judged sample and shown in the coverage table. A product sold under different pack sizes is not matched as the same product.
