Antiques, jade and communist China memorabilia can be found in Dongtai Road Antiques Market, where you must bargain if you want to get a fair deal. Yuyuan Gardens is another good option for antiques as well as all manner of cheaply made and priced souvenirs (teapots, paintings, "silk" bags, etc.). There are two basement markets. You will have to hunt for them, but they are worth the effort. As with any market in China, don't be afraid to bargain to get a fair price.
