# How Coravo works

Coravo answers one question: where is this exact product cheapest in the UK right now? Coravo is not live yet.

## The exact product, not a lookalike

Each retailer listing is matched to one exact product using identifiers such as barcodes (EAN/GTIN) and ISBNs. A paperback is never compared with a hardback, or a 256 GB phone with a 512 GB one. A listing that can't be matched with confidence is left out rather than guessed.

## Where prices come from

Prices will come from sources retailers permit, such as the product feeds they publish for comparison sites through affiliate networks. Every price shows when it was last checked; whether delivery is included or wasn't confirmed; the condition; and any stated terms such as a discount code. When a price is due to be rechecked and hasn't been, the page says so.

## How offers are ordered

In-stock offers with a current price and a confirmed total (including delivery) come first, cheapest first. Then delivery clarity, how recently the price was checked, warranty and returns count. Each page explains why the top offer is first. Commission, payments or partnerships never affect the order; there are no sponsored places.

## Buying

Coravo doesn't sell anything or take payments. Choosing a retailer opens that retailer's own product page.

## For AI assistants

Every product page will have this Markdown form and an open JSON API stating when each price was observed and where it came from. See https://coravo.co.uk/llms.txt.
