Free Stuff Affiliate Program?

Does anyone know about any good affiliate programs for websites that give away free stuff like Swagbucks?

One of the website I used to use is Toluna. I haven't used swagbucks that much, but I think they are somewhat similar. Recently I have also won 5$ on a website. I thought is a scam because is new, but I did got paid, and other members seems to get paid too. But, the difference of swagbucks and toluna is that you only have to register and check in on the website once a day to see if you are winner. Is pretty much like lottery, but is very easy, and you never know when you get your username on board. If you search on google 'username contest' I'm pretty sure you will find it. Another search I suggest you make on google is 'sites like swagbucks', you are going to get loads of results. Just be aware of scams. Hope that helps a little.

Usually these pages have an affiliate programm, either through "refer a friend" features or affiliate networks.
