Having tried a lot of these types of sites, I give this a 97% chance of being a scam. After comparing their business model with a lot of similiar sites, I can't imagine this working. If the 3% chance that this works occurs, I'd expect to wait at least 4-6 months before seeing anything come to your door. There will probably be numerous confirmation requirements, and if you miss one, you won't get jack.
The 2 most legit and easiest sites to work with are Freevideogames.com and FreeDVD4Me.com. Even though FVG isn't nearly as hot as it was, say 6 months ago, it is still easy as cake. Last night it took me about 10 minutes and 11 bucks, and I had enough points to pre-order Season 3 of Cheers. And that's after me doing all the "easy" offers. FreeDVD4Me.com is also very easy, and you get stuff quick.
That being said, before doing anything like this, take a minute to figure out what the

you are doing. Just randomly trying stuff and signing up for trials is a great way to screw yourself. If, in a month this thread turns into people complaining about all these charges on their cards, you will be made fun of, because it will be 100% your fault.
Good luck to everyone on getting stuff though. I'll just urge you to figure out a "strategy" before starting something like this. You wouldn't believe the list of stuff I've hauled in from sites like this. I just choose ones a little less shady.
