Power Tab accessories

So, you have this great tablet in the market which I bought not realizing that it can be bought as a bundle with the keyboard. Yes I'm talking about the Powertab. I've looked everywhere for the keyboard and I mean everywhere. None of your stores have it and can only sell it to me as a bundle. Now, how is it that you can sell this wonderful product and not its main accessory separate? Somebody point me in the right direction. Please...
