Hi, Everyone!
       After being in New York and seeing deliveries being made to homes, here are two sources, you may want to check out as a gift idea to Steve and Kate upon the arrival of their new daughter:
Fresh Direct and Pea Pod.  They service the New York area and I saw them make deliveries in Riverdale.  It might be convenient for Kate (or Steve) to order online and have the groceries delivered to their door.
        Only a little over one week to go!  Am I excited or what?!
         The Happy Nana
