This is a game for all you Big Spenders out there.

I will give you a sum of money and all you have to do is spend as much of it as you can aren't I generous?!

Your aim is to get as many items as you can and be left with the least amount of change.

Notes:
* The money is is English pounds, but that isn't a major issue
* You will need the Shockwave plug-in, available from the website.
