Okay, I'm going to start with reviewing points2shop since it seems as if it was the most commonly voted for out of the various options.
I am going to make a video later if anyone requests so, but for now I am just going to review it with words, and explain how it works.
With Points2shop ( http://www.points2shop.com/?ref=finkrocks44 ), you can complete offers, play games, or refer others to earn either cash or prizes from amazon. I personally have made almost $150 bucks with it, as can be seen through my profile on their website. Some offers will only earn you points, while others will earn you cash. Cash can be converted into points, but not the other way around. 100 points are equal to $1, and points and cash are converted at a 1:1 ratio, meaning it is still valued the same when you convert from cash to points. Cash can be withdrawn through paypal, checks, or basically anything, but points can only be withdrawn through gifts from amazon. It's not that hard to make points, and with 2 days of trying, I was able to get a game from amazon from them. If you click on the link ( http://www.points2shop.com/?ref=finkrocks44 ), and sign up, you automatically start out with 250 points, equal to $2.50 (Must be from the US, England, or Canada I believe, but I am not 100% sure.), and they have the option to receive $1 with 100 points so you can test them to make sure it works. If you choose to get the dollar, when you sign up and confirm your email, you just need to go to their prize section to redeem it. You put in your address and they mail it to you. I highly recommend this site, but if you're a little iffy, upon request, I can put up pictures of the prizes I won, and you can see which prizes I won from their website. (I can't put up pictures of the used giftcards, or the airsoft gun since I don't have them anymore though :P)
