Stop & Shop is a grocery store so their core business may be unaffected but if smoking shoppers have a convenient alternative that also sells cigarettes then Stop & Shop will probably lose a customer.
Maybe. I can’t imagine that it’s a big number. I doubt anyone goes ”Hey, I’m gonna start shopping at S&S because they quit selling cigarettes,” any more than someone saying “Never again.” Cigs and beer seem to be competitively priced just about anywhere. If I needed feeder goldfish on the way home, I doubt S&S would have them. The pet store likely would...and they sell cigarettes.
