Forbes.com has the skinny on Luxury Plastic: those select, mythical cards issued to an elite few who spend a mere $250,000 a year and put it all on plastic. Unbeknownst to the masses, invitation-only cards like the American Express Centurion card (aka "the Black AmEx") and the even rarer Coutts & Co. purple card (try 100 card-holders) offer truly luxurious rewards programs. According to Forbes, the purple card is the most prestigious of them all (after all, this is the bank to the Queen we're talking about):
World Card is offered only to Coutts clients, and you have to have millions to qualify for that status to begin with. Aside from all the typical travel upgrades and luxury services, the card comes in handy when you need to go shopping at your favorite department store in the middle of the night. A quick call to a World Card service representative will arrange a private after-hours shopping session anywhere your little heart desires.Ahhh, the perks of (purple) plastic.
