I saw at one eshop that when you buy an XBOX you can customize on the fly which model do you want, how many joysticks do you need, which cables etc. and the price depending on the selection was changing on the screen.
Take a look at these pics I took:




Depending on the items selected from the dropdown menus - the correct price is calculated at the same moment.
Can IP.Nexus do that?
If yes then can you tell in a few word how to do it? Wanna test this at the demo site.
BTW how come nobody answers to presale questions when filling an online form on IPS website?
