Taobao is your friend. Everything is cheaper online, unless you can find a local shop that is willing to haggle and get the price down. For instance, the KBC poker on Taobao works out to I think $90 shipped, but in the computer shops that even have them, it's nearly double that.
You'll need an Alipay account, but you can use it like escrow. You "pay", but you only release the funds when you get the item. Most sellers on Taobao accept this form of payment, since it guarantees that you have the funds to them, and that they have the item to you. If the item is incorrect, you just send it back. As soon as they receive it back, they mark it returned, and your money is returned to you.
Alipay is a lot like paypal, but with more features in some ways, fewer features in others. For instance, as of May at least, you couldn't transfer from Alipay to your bank account.
Edit: Oh, and this is true of just about anything, by the way, not just electronics. The disparity is markedly higher than it is here in the US.
