When shopping for car stuff in the Rugby branch of Tesco, I found a Homer Simpson Visor Organiser in the clearance section for £2.50. There were loads left - strangely without a yellow Reduced sticker.
Holds up to 8 CDs, also business cards and travel receipts.
Probably not available in all stores, but worth looking out for as a cheap Christmas present or something.
Not available on Tesco Direct, but sells for £9.99 online here:http://www.click-parts.co.uk/files/details.php?id=344
