How can I buy a product key for Microsoft Office 2007?

[Jaisal]

I bought a new Acer laptop about 1 and half months ago that came with Vista and Office 2007 TRAIL preinstalled. Now as the trail is about to expire I want to buy a Office Professional 2007. But that will put some extra work for me like uninstalling and reinstalling etc. Hence I was thing if there is any way I can buy license key from Microsoft and convert this trail in full version. I tried searching for the same but dint found the place where I can but the license. Any suggestion please?
