I grabbed this advertisement out of The Fowlerville Review from the June 26, 1929, issue. This Kroger store was located in the northeast quadrant, possibly right next to the pharmacy. I never did find an address. One of its employees and eventually manager was Stirling Douglass. Some may remember him--he was very active in the community. He eventually opened his own grocery store as well as running the Twin-Q Inn in the 40s.
Wouldn't it be lovely to get groceries at these prices!
