Whether you envision buying half of Paris, or simply enjoy the wealth of window-shopping opportunities, Parisian shops are an integral part of the city's cultural identity, and make it the ultimate destination for the discerning consumer. Those fortunate enough to be visiting at the beginning of January or the beginning of July during the sales, may take advantage of substantial discounts, ranging between 30% and 50% on clothing, shoes, accessories, and furnishing fabrics. Almost all retailers can provide you with a "détaxe" form, to claim a refund on the 18.6% sales tax if purchases exceed a certain level; this form should be presented to customs upon leaving France, and you should expect your refund within about six weeks.
