Freebie trading uses hundreds of websites called "Incentivized Freebie Websites" (IFW's). IFW's present trial offers from hundreds of companies that pay the IFW site commissions to advertise their products and services. The IFW's provide an incentive (cash or prizes) to people for signing up for the trial offers and getting a certain number of referrals to do the same. Types of prizes include playstations, Xbox360s, computers, TVs, and CASH. The types of prizes and cash amounts vary depending on the particular IFW site.

How it works.

IFW's get paid the commission from their sponsors on every person that signs up and completes the sponsors trial offer. For instance say Blockbuster uses an IFW to advertise their offer for a 30 day trial for a service to get movies delivered to you through the mail. If you like the service, after 30 days you get billed each month at the regular price. If you don't like the service, you can cancel before the 30 day trial period has expired, and that ends your subscription to blockbuster's service.

However, since you signed up through the IFW, you are credited on the IFW for 1 credit which qualifies you to send referrals to the site and collect the prize. (Some sites require you complete more that one offer to get 1 full credit).

Blockbuster is just an example, not all offers require you to pay for a trial period for their products. Some just require you to pay a small shipping and handling fee, others cost nothing at all. Even though many of the offers cost money, it is much less than the money you will make by completing the offer.

How do you make money by completing the offer?
Freebie traders pay you to complete offers!
Completing a site's offer requirements to gain a credit is known in the freebie trading world as 'going green', or 'greening'. If you sign up for an IFW site via another trader's referral link and complete that site's offer requirements for a credit, you 'went green' or 'greened' for that trader.

Typically, traders will pay you between $15 and $75 for 'going green' depending on the difficulty and expense of the site's offer requirements, prize value, and amount of referrals required.

How can a trader afford to pay you more than you spend on completing the site's offers?

It works like this:

Once you complete the required number of offers (go green) on an IFW, the site is "yours", and it gives you a referral link that you can use to refer other people. You have qualified, and now all you have to do is get enough referrals to sign up (through your referral link) on the site and complete the required offers or 'go green' (just like you did), and you can collect the prize.

Lets say the prize you picked was in the form of $200 in PayPal cash (a typical cash prize), the IFW says you have to get 5 referrals to receive the prize. If you think about it, they are basically paying you $40 per referral at that point. You could pay 5 people $20 each to complete the site's offers (go green), and still pocket $100 in cash.
