We do a combo...depending on who has what we order most of the booze/beer/seltzer/wine through Caribbean Cellars. We order water and all of the heavy stuff through Riteway. Once we arrive we shop for the other stuff at One Mart or Riteway with a stop off at the French Deli! If you are shopping at Riteway for beer or seltzer make sure to check the store connected to it (forget its name). They often have bulk items and usually have more selection of drinks.
