Have you recently checked out the Grocery Store Database? This is a list (which is continually growing) that has links to grocery stores all over the country. We recently added:
HEB – TX
Publix – FL
Kroger – FL
If you don’t see your store included, drop me an email so that I can try to get them added for you. If you are a blogger who does a match up for a location not already included, email me with your site name, static link (via tag or category) and the state/region where you are located and I will add you as well! My email is email@example.com.
