I had to ask because Wegmans and Plainville are names not common in Minnesota, if at all.
They are a Rochester, NY based family business that has expanded across the north east and down into VA even.
They are most prolific in NY between Buffalo and Syracuse. Their big store in DeWitt is the furthest east one until you get to Boston, where there are a couple sstores.
When my oldest moved to LA, all the NY transplants would would bemoan that there were no Wegman’s. It was the hing they missed the most about NY.
Her CA friends would ask what the big deal was about Wegman’s and she’d tell them to think Trader Joe’s with three times the quality and half the price. (that means something to a millennial)
