The Official Jamiroquai Store is running a promotion throughout the month of December:

If you buy anything in the Jamiroquai store during December 2005 you will be entered into a prize draw to win a signed tour jacket. As a runner up prize we have 10 signed CD's. So, if you haven't done your Xmas shopping yet then now is your chance to win one of these super rare jackets.
