How does this work?
This is a new form of marketing created in the USA and now available to those in the UK.
Companies such as AOL Broadband, Which? Magazine, Jackpot Joy, Cahoot, Gala Bingo and LOVEFiLM pay the giveaway site to advertise their offers.
In order to fulfill the requirements, you have to complete one of the selected offers. Therefore, the giveaway site reward you with hi- tech goodies.
By referring your friends you are providing the advertisers and the company with more business and that is why you are rewarded.
The reason that you are getting these for free is because the companies which advertise their offers on this sites pay for every person that you get to sign up.
For each person the company pays the networks £20-25. So For each gift you are having to get a certain number of referrals. For the xbox 360 you need 14 plus yourself makes 15.
15 X £25= £375.
This pays for the gift you are receiving plus leaves the network with a bit of money left over
