Membership definitely has its privileges, but good luck getting the Centurion, the Black Card from American Express. The fantastic plastic has a $1,000 annual fee and has been available since 1999 but is now generating buzz thanks to articles focusing on its snob appeal on dailycandy.com and in society rags like NYC’s Gotham. ”This card was not designed for everybody, so we’re not advertising it,” says American Express spokesperson Judy Tenzer. As for getting on the black-list: ”We don’t disclose those requirements,” says Tenzer, who adds that select Platinum-card customers are invited to join the Centurion crowd. (Still, we’ll bet company endorsers Tiger Woods, Jerry Seinfeld, and Magic Johnson have been carded.) The benefits of basic black include automatic enrollment in elite flying programs, free upgrades at select Four Seasons hotels, and something sure to tick off PETA: free fur storage at Saks.
