*cough cough* union busting *cough cough*
Ahold and UFCW are both terrible. See Stop & Shop and Giant-Landover for what these stores would look like unionized.
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.
