As requested by @BrianClasby, here are the first 10 items I would buy if I won the $403 million Powerball. As a disclaimer, I know the right answer is to first give to charity and give to others, but that's not a fun list.
  1. Miami Beach house
  2. Newtown Square, PA house
  3. Tribeca loft
  4. East Hampton cottage
  5. Rolls Royce Ghost
  6. McLaren 675LT
  7. Richard Mille RM35-01
  8. Audemars Piguet Royal Oak Ceramic Perpetual Calendar 26579CE
  9. Patek Philippe 5370p-001
  10. Liberty National initiation fee
  11. Left with $155mm assuming 50% tax rate. Not bad!
