There's another scam that I know goes around for iPods.
You get a link to a site that claims to be able to get you what you want for 1/10th or some other fraction of the price. Paying this money adds you to the bottom of the list.
When x people join the list, the person on top gets an ipod. So the people who join early get cool stuff cheap and the bottom people get screwed. And the people running the site get money in the process too.
EDIT: here's a link with links to such sites and a longer explanation:
