Who would want to buy them?
Wegmans should come to Long Island so they can show Ahold and A&P what a real supermarket is.
There are a few, but some of them are kinda awful (Bay Shore, and the Janson's ones in Patchogue and Hauppauge). The best SR on LI is in Commack, right off the LIE.
Ahold - the little engine that could, but won't do.
I'm actually surprised Wegmans hasn't entered Long Island, downstate NY, or Connecticut. You'd think they'd do gangbusters business - plus in certain areas, competition is weak.
