I’ll repeat, China has everything. But I would avoid electronics (anything from cell phones to cameras to anything else), as those are usually heavily taxed and more expensive than Amazon. But clothing is cheap and good (if you avoid the American-like shopping centers).

You could always opt to get a fake Louis Vuitton bag, they sell buckets of those for $30 USD and they look pretty legit. The list goes on, and without knowing your tastes or personal interests, this is a tough question to answer.
