Open food fact recently launched Open Prices (https://prices.openfoodfacts.org/). It's currently crowd-sourced instead of an automated crawling, but prices are localized in space and time which could lead to intersting results. This will lead to an open database of food product prices.

It's a neat idea, but I think you need some automation to make it useful over a long period of time. There's a website to do track gas prices, and they just change too much to keep updated.

Localized pricing just adds noise to data. Intermittent updates combined with possibility of input error also creates issues.

Retailers that utilize price zones typically have the baseline price that drives the prices for each price zone (e.g. set prices in California to be 10% more than baseline). Getting the baseline price in an automated way is the ideal solution.

This is super cool! I'd hoped to build something like this.
