What does the Product Configurator do?

I’ve been browsing through the forums, and there seems to be a lot of people raving about the Product Configurator. But what do you use it for?

y) Buy a Stock Car = $y

x) Upgrade to tinted Windows $50

x) Upgrade to 15" Chrome hubcaps $1500

x) Upgrade to Doof Doof Stereo $1500

x) Upgrade Girlfriend $0

Total cost = $x+y

User gets to choose what they want, like a PC being build to suit.

If you check alienware computer configurator you get an idea of what you can do with Product configurator.

Very nice feature.

Very nice feature indeed, but it can be a PITA to figure out how to set up.
