The Mega Millions Jackpot is now half a billion dollars. If you didn’t happen to invent Facebook, you’re probably thinking that half a billion dollars could come in handy. You’re probably already dreaming how you’ll spent the dough; jet packs, pet unicorn, hiring Mark Zuckerberg to personally update your status on Facebook. In case you haven’t earmarked every dollar, you might want to pop into one of these little shoppes and pick up a few things. They just happen to be the 10 most expensive stores in New York City.
