I was at Harvey Norman (Broadmeadows, VIC) yesterday, and they had a large table with some iPhone/iPod, computer, gaming accessories on it at cheap prices. Most of the stuff wasn't really worth it, but the lens cleaning kit is pretty good for $3. They had about 20 boxes easy, so if you are near the place just pop in and grab one!
I got 3 as I know a few people who have a Wii and never use it (including myself), so it may come in handy if dust gets in there somehow. I also saw this one guy in front of my who picked up 7 of them! I'm pretty sure it was broden, as you can see there are some on eBay for around $15. They are normally $9.96. Tsk tsk.

Cheap but a waste of money. Once a pick up (laser) assembly gives up the ghost no amount of "cleaning" will fix it permanently.
