iPyramidScheme
Yes, it’s a pyramid scheme. Yes, the last person to sign up gets rooked. However, it’s not there yet, and I know people who (claim to) have received their iPods. So: Free iPods
The idea is that you sign up for an “offer” (usually a credit card application, or sign up for eBay, or buy something from PetCareRX) which gives your referrer a credit. Then, you recruit five people to do the same for you. When you get five credits, you get a free iPod.
Warning: Sign up with a disposable email address. It will will be sold for spam. I have virtually unlimited Gmail invites to give out to anyone who wants to do the Free iPod thing. Just ask.
