How proof works

A dramatic-looking discount never outruns what our records can actually establish. These are the rules every deal must pass.

Where a price can come from

The four labels

OBSERVED DROP RETAILER-LISTED VERIFIED IN STOCK EXPIRED

They are deliberately not interchangeable. Observed means our own records prove the price was higher. Retailer-listed means the store claims it. Verified in stock means we just checked the exact item. Expired means the deal ended. It stays on the record instead of being deleted.

Publication rules

A deal's life

01

Withheld until verified

A candidate stays private until its source, exact variant, current price, and availability pass the rules above.

02

Published with its source

Every published deal says whether the history is ours or the retailer's claim.

03

Live only while fresh

The shop link appears only while the exact item has a fresh verified price and stock state.

04

Expired, never erased

A price change or sellout marks the receipt expired. The evidence stays.

The record itself

PriceCrater began retaining product-level price, stock, and retailer-claim changes on August 18, 2026. We won’t pretend to have history we don’t. Charts and evidence pages appear only once the records can back them.
