The price record
A sale price anyone can check.
Every price your shop lists goes into a public record built so that changes show. Shoppers and AI agents can check a sale for themselves.

Why now
AI agents repeat your old prices.
An agent tells a shopper what they save. On Storeware it can check first, and so can the shopper.
On your product page
One line, and the proof behind it.
A reduced price shows the lowest price before the sale and how long it stood, with a link to the full history.
Anyone can check it
Nobody has to take our word.
Outside services stamp the record every day. Anybody can keep a copy and check it with a short open script, so a rewrite would show.

What it does not show
It shows prices, not sales.
It does not show that anybody paid a price or that a thing was in stock. It does not cover discount codes or trade prices, and a shop can choose not to show it.
The next shopper sends her AI first.
