Assembling all of the prices

Did you know; there's only around 800 supermarket chains in the world (notable enough to get into wikidata), and only about 200-300 of them offer some kind of online shopping capability? Of those, 110 offer schema.org terms.

Sadly, very few of those publish a GTIN (barcode).

Side project for the week has been scraping all of the grocery sites to build an open index of prices; complementary to OpenFoodFacts' open-prices data.

The ultimate intent is to try and glue it together with ODNC APIs and build a plugin for mealie/home assistant's shopping lists.
