In this page there are links to the websites that will get you your free items, but i would suggest that you look at the "how it works" page first.
Click on the free item that you want. You will be taken to a site where you should sign up, complete an offer then start referring people! The more expensive the item you pick, the more referrals you need to get so i'd suggest starting off with something like a games console or an iphone then get a tv or a laptop later.
