How a verdict is made
1We record, dailyEvery tracked product is price-checked at every store at least once a day. Each check is stored, so every product carries a full price history.
2We compare to historyToday’s price is judged against its own 90-day record: average, real low, and how long "sales" actually last.
3We call it honestlyReal deal, typical price, or inflated. The verdict links to the data behind it and never to whoever pays us more.
