I hop on the light rail (I live 3 blocks from the LSP stop) and ride to ShopRite or the Whole Foods in Weehawken. I tend to go to the ShopRite in Hoboken (9th st stop) because the one in Jersey City (Harsimis Cove stop) is pretty miserable and the Hoboken staff are much nicer and helpful. I'm also just shopping for one person, so I'm not carrying much. I also like to pick up random things I need from The Grind General Store on Suydam and Communipaw. I was able to throw together a last-minute dinner for four people for less than $50. Pasta, sauce, cheese, saussage, mushrooms, broccolini, onions, tomatoes, and garlic all purchased there.
