The members-only sample-sale site Gilt.com just launched an even more exclusive club called Gilt Noir, which lets the top one percent of users preview sales fifteen minutes before they go live online. In addition, the initial 2,000 Noir members, which include Gwyneth Paltrow and Google vice-president Marissa Mayer, also have access to special events like wine tastings and cooking classes. To become a Gilt Noir member, you must spend at least $10,000 on Gilt.com a year. So a members-only club that has an elite members-only section? They just one-upped themselves. You in?
