British-born, New York-based Mark Ellwood is a journalist who specializes in writing smartly about stupid things. He has contributed regularly to the Financial Times Weekend and How To Spend It Magazine, T: New York Times style magazine, Wall Street Journal Weekend, and Departures, among others. He has interviewed the world’s oldest supermodel (she’s 80 and counting), trekked to a $10bn art island in rural Japan that looked like a Bond villain’s lair (he brought his own white cat), and spent a weekend in an all-psychic town (and yes, they did know he was coming because he called). Ellwood’s new book Bargain Fever: How to Shop in a Discounted World will be published by Penguin-Portfolio on October 17, 2013. In this book, he examines our culture’s newfound obsession with deals, discounts and never paying full price (like the unadvertised discount savvy shoppers can wrestle out of Prada staff with a few choice words or the woman who earns more than a $1m a year reselling coupons).
