Freebie Companies get paid by advertisers to get new customers to take part in their offers.
Every person who signs up to a freebie site must complete an offer, the companies who provide the offers pay the freebie site for getting them new customers.
The average amount that the advertising company will pay the freebie site for a new customer is £20-£30. So when you work it out the number of referrals ad's up to around the price of the item.
The reason that companies do this is because it’s an easy way for them to get new customers.
PLEASE REMEMBER THAT YOU CAN NOT SIGN UP TO THESE SITES ON SHARED COMPUTERS THAT HAVE THE SAME IP ADDRESS OR HAVE MORE THAN ONE ACCOUNT PER HOUSEHOLD!
(because when your account is verified [when you have all your referrals] you will be declined)
So make sure you are on a private computer and nobody else signs up under your internet connection.
