One of the things that dissuades a lot of people from trying to get a freebie like a Free iPod is getting those referrals to complete the requirements. Fortunately there are several ways to collect the referrals required to receive your freebies.
Chances are, you have a lot of friends and family who would like a free gift just as much as you do. A good place to start is your contact list in your email. Send out your referral link to your friends with some information about the site you are working on so that they know that it is legitimate. Remember, don't spam your link to people you don't know, and be aware that only one account per household is allowed.
Create a site like this one. If you have a blog, or a personal website, include your referral link with some information about the site to encourage people to sign up.
Let your online buddies know about your quest to get a free iPod. When they see how easy the offers are and how quickly you can get referrals, they will be happy to help you out just to get a chance to try it out themselves. Don't spam your link!
There are a lot of people out there just like you, who want to complete all the requirements for their items as soon as possible. If you are just starting out at getting freebies, you hold a lot of power because you haven't signed up for many sites. Lots of people are happy to trade a referral on your site for one on theirs. Not only do you get to sign up for another great freebie, but you get a referral in the process.
