These sites are based around Affiliate marketing.
Companies pay the site £25 for each person that signs up to their offer being advertised.
If you want an iPod, then you will need to refer 8 people to sign up and complete one of the offers. So if an iPod is 8 referrals then that will be 8 x £25 = £200
You also have to complete your own offer which will add another £25 to that making the total money the site gets £225.
This pays for the iPod which retails at about £170 and leaves the site with enough money left over to make a profit.
If you are still unsure then please visit our proof section which is complete with images of my personal freebie site gain over the past few years.
