Paris' puces, or flea markets, are some of the largest (covering seventeen acres) and busiest (more than 50,000 visitors per weekend) in the world. You can go it alone and risk getting lost or swindled. Or you can hire ex–New Yorker Rachel Kaplan, a self-proclaimed shopping expert, to help you nab hard-to-locate treasures. Kaplan has lived in Paris for a decade and written two Insider's Guides to her adopted city. She leads private tours ($500 for one to six people) to the various markets and will help you haggle to get the best prices, as well as arrange for shipping back to the States. Schedule your tour on a Monday or a Friday morning to find the best bargains.
