A price is a dated observation, not a promise
Retail prices change with promotions, configuration, region and stock. WhatItCosts records the amount shown by a named retailer on a named date, then keeps that date beside the number. A price without an observation date is a rumour.
The observation date is not a guarantee that the price is still available. It tells you how old the evidence is so you can decide whether to check the retailer again.
Retail, reference and estimate mean different things
A retail observation is a price shown by a retailer for a specific product or configuration. A reference price is a launch or list price used as a comparison point. An evidence-backed estimate is derived from sources and is labelled as an estimate, never as a local offer.
We never convert a reference price into a local currency and present it as a price you can pay. Currency conversion adds a date, a rate and a fee model, and none of those are the retailer's price.
Verification is separate from the product's status
A product can be published while one of its prices is still marked unverified. The product status describes the record; the verification status describes the evidence behind a particular price.
If a price is marked unverified, treat it as a lead to investigate rather than a number to quote.
