It is from their weekly flyer page

And then what do you do to get the data onto the map?

[ayocado]

Plotted using Leaflet. A python script creates separate HTML file for every product that has a price differential across stores (many products do not have any price difference across the country). Hosted as a static site.

So you download each state's flyers?
