What are some sites that offer freebies?

There's a site called Teen Freeway I'm subscribed to. They send me newsletters when there's something free for me to get. I get what they promise about 5/8 times. You don't always get what they say you will, but they don't spam, and you usually do, so it's good. So far I got free subscriptions to a bunch of magazines, and a ton of free samples for things. I'm not sure of the URL, so I'd Google "Teen Freeway" and see what comes up. You have to be 13+.
