How it works?
Websites make money from people like you when you and your friends complete offers for websites such as coral bet and love film through there site. Therefore as an incentive to complete these offers etc, they offer gifts anything from apple ipods to lap tops.
How many offers?
Offers or Referalls change depending on the price of the gift and ipod shuffle in most cases is 2 referalls whereas a laptop can be anywhere between 20 and 36.
Is it a scam?
Many people will reiterate the point that these websites have been on television etc i find the best place for reinsurance is http://www.exceem.co.uk/ which is the online freebie community full of helpful and successful freebie participants.
Where do I start?
