There’s a supermarket in the South East called Publix. They made a habit of providing clean stores, great customer service and a reasonable price.
They are beating Walmart in the grocery sector and put other supermarket chains out of business.
They aren’t the cheapest but they are always busy.
Went through Jupiter, Fla., on our honeymoon and discovered our first Publix. Great place, and best doughnuts in the known world. Wish they'd come north.
