One inbox, read by a person. Wrong price, missing shop, a chart that looks off, or a question about the data.

Wrong price?

Send the product link from this site and the price you saw. Prices here are what each supermarket advertises online, refreshed daily, so the shelf can differ. If the online price is wrong, that's a bug worth reporting.

Using the data?

It's all on the open data page under CC BY 4.0, as files and as a free API with an MCP endpoint. Built something with it? Send a link. Need a cut that isn't published? Ask.

From a supermarket?

Kia ora. The crawler is rate limited, runs off peak, and never hot links your images. The site shows your own advertised prices with your name on them. If something is a problem, email and it gets sorted.

Want to help?

Not with money, see funding. Sharp eyes on the data are always welcome.
