A couple years ago, I signed up for a site that gave away free iPods. All you had to do was complete some “offers” and get other people to sign up through your referral link. I was able to get enough referrals, but I never did get the iPod because I didn’t have a credit card in order to complete the offers.
There’s another site out there where you can get a free iPod Nano by doing the same thing (completing offers and getting referrals to sign up). The difference with this one, however, is that you don’t need a credit card to complete the offers.
I already have a Nano, so there’s no reason for me to participate in this kind of program right now, but I thought I’d pass it along in case any of you readers out there want to look into it.
