Wegman's is to grocery stores as Mecca is to Muslims.
Case in point.
$540 can buy you a boat load of stuff at ANY grocery store. It depends though; Wegman's specializes is "prepared food" as much as it does in organic and international stuff. Obviously you'll pay a premium for anything that is of higher quality, but I can spend $100 at Wegman's and spend a week in culinary bliss. Prepared foods are most expensive but unconscionably convenient. Organic food is "doing your part" and international/gourmet is more-or-less trying something new or venturing into uncharted culinary waters. Sure, you can make yourself some Pad Thai, Ahi Tuna Sushi, or Pho Soup, but still probably won't be as good as the real thing.
My advice when shopping at a Wegman's; prepare to take some time because shopping there is an experience. If, like most people, you generally abhor grocery shopping then my suggestion is to skip and head over to your nearest Shop Rite/Giant/Martins/Publix/Albertsons/Winn Dixie and go to town. I don't even know what the grocery stores are called west of Ohio. Otherwise; just browse. Get something different and, if going after raw ingredients, go in with a game plan. Wegmans' butcher and seafood is top-notch so if you want a steak; now is the time. And the "expensive" cuts are, er, expensiver (bear with me). Screw it, get a thick porterhouse and go to town. You have $540!
