Yoox.com: My latest online shopping secret is Yoox.com. Save as much as an extra 50 percent off spring and summer designer apparel, footwear and accessories from top brands like Valentino, Givenchy, Marni, Gucci, and more. I found an understated, funky Bikkembergs high-top sneaker at a steal ($49, retail $165). Sale ends Saturday.
