Many urban areas have to deal with a problem of not enough supermarkets, especially in poorer areas. I’ve heard, but don’t know if it’s true, that Detroit doesn’t have a single national supermarket retailer. In Boston, the North End (not poor by any measure) has been searching for a major supermarket for years. In DC, large portions of the center have no access to large grocers. This phenomenon is called a “food desert” and a lot of time is put into trying to lure retailers into under-served areas.
Fresno is not like that. Oddly enough, Fresno is jam-packed with huge supermarkets, many in very close proximity. Here is a list of most (I may have forgotten a few!) grocery chains that serve Fresno. This doesn’t include small, local stores. All of the following brands are major chains with multiple locations in the area.
