Most of us have a taste for the high life, but not often the budget for it. Luckily, Gilt Groupe stepped in to fulfill our need to indulge for less. Founded in 2007, Gilt Groupe operates the flash sale site Gilt.com. The secret to its success? Since you must be a member to shop, it has the same feeling of exclusivity that you get with a private boutique. It’s free to join and its mega-buying power allows Gilt.com to offer designer brands at a discounted price. Do you need to own a vintage Louis Vuitton bag? Get it on Gilt.com for up to 60% off. New sales featuring apparel, accessories, toys, beauty products and home goods begin daily. Sales last 36-48 hours, or as long as the inventory lasts, so you have to be quick. Gilt Groupe also offers deals on luxury travel accommodations through its site Jetsetter.com.
