I've gotten some amazing things from these sites. Swag Bucks requires almost no work to earn. Just search Google like you always do, and you're earning bucks in the process. In a short time, you'll have enough to redeem for gift cards, shirts, books, music, electronics. Doesn't take long to rack up a room full of brand new stuff.
Listia - similarly, you can earn credits here by doing very little. I call it the "Free eBay", because a simple visit there will let you claim free goods in auctions that cost nothing. No, these aren't those lame penny auctions that suddenly become 100 dollar auctions - there are real things here being given away every second for free. And if you want more credits, just post something you don't want anymore - set your opening bid, and get them right away!
