Many people recommend Nanjing Lu for shopping in Shanghai. This is a good place, if you're looking for high-end goods and the big brands. But you can find these shops in major cities around the world, and you're not going to find it any cheaper in Shanghai. Along Shan Xi Nan Lu, there are entire streets of shops dedicated to outlet fashion. Many big names manufacture in China, and these shops carry factory overruns or samples, so sometimes you get stuff even before they are launched in the new season. You can get clothes and shoes at a very reasonable price, but as with normal outlet shopping, look out for manufacturing defects. Another great street is Huai Hai Zhong Lu and Chang Shu Lu. Similar concept as Shan Xi Nan Lu, just even more shops to choose from. You just got to be mindful that some shops sell the real thing, but some others sell fakes as well. So if you have a local friend who's into the shopping scene, try to get tips on which shops to go to. Bring cash as well, as many shops don't accept credit cards.
