You gotta find the right surveys to do. I always go for offers that are 50+ points. I got like 1700 points in a few days to a week, only doing it for maybe an hour or less a day. That's $17 right there. The trick is to know what offers are best, and offer the best point/time to complete ratio. I also like to find offers in the recently completed offers, a lot of those are good.
I have received pokemon cards from there before. Right now I'm saving up to either get a box of pokemon cards ($80) or a PS3/PC game. This site is real. The only catch though, is the shipping. When you have an order of let's say 1000 points, so $10, the shipping is half of it almost always. Usually on every order shipping is around 300-600 points. But when you're getting a more expensive item it won't really seem like much I guess.
