mik5: I am taking your questions seriously. ShopRite supermarkets are franchised so technically each store is independently owned (although one operator can have more than 1 store). So in answer to your questions:
Shoprite is owned by Yidden? the one on McDonald Ave. – Yes
Who are not frum? To my knowledge they are not frum.
Really? Is there chametz for sale in Shoprite right now? – In that ShopRite, yes. They sell their chometz thru Rabbi Beck and as R’ Moshe TZATZAL Paskened, the mechira is still a valid mechira for what was purchased before Pesach.
