This is another GPT site I use called Rebelbucks. Rebelbucks has more of a focus on straight up cashing out for your money. I believe they offer paypal+amazon gift certificates. In comparison, rebelbucks had the better referral system. I've only recently started using the site, so I'm not sure how it fares in comparison to other sites I've used. But so far I have five points on rebelbucks and still going :D
