Welcome to FT, haydengr! If you have a China visa, consider going to Shenzhen (Lo Wu market) for your fakes, bet they'll be lots cheaper than in HK. However, not usually worth it if you don't have a multiple entry visa already.
It's a lot like "Alice's Restaurant" -- you can get anything you want. For example, I was in Shenzhen a few weeks ago and was approached by several street vendors selling very professionally packaged versions of Windows 7 -- which isn't even close to finished yet at Microsoft and hence doesn't even exist.
