How the sites were ranked
The GPT sites were ranked upon their overall payout and diversity of the payouts, the amount of help available, and the number and overall reliability and ease of use of the site. All of the catagories were rated on a scale of 1 to 10 then the the three catagories were added together to get an average. I updated these rankings on November 10, 2011.
#1 Points2shop/Cashle
Points2shop and Cashle are easily the best version of a GPT site that exists. If you sign up for either site you are signed up for both. Cashle lets you earn straight cash and can be payed out in a check, Paypal, or many other gift cards. Points2shop allows you to buy with available on Amazon.com. These sites offer forums provide help, information for contests, and a social forum. With a vast amount of earning opportunities, completing offers, lotteries, weekly and monthly contests, and games, it is possible to earn $50 to $200 dollars a week.

#2 Swagbucks
In a distant second, Swagbucks offers a mediocre service and provides a smaller payout. Swagbucks offers one realistic prize. They offer a $5 amazon gift card for a reasonable price but with most prizes it actually costs a fair amount more to buy the prize on their site than to buy a sufficient amount of the $5 gift cards and buying it on Amazon. However they do have a significant number of ways to earn Swagbucks. There is little to no help available.

#3 Cash Crate
Once Lockerz stopped really being a GPT site I have looked for another site to suppliment my income. I found Cash Crate. While you still get paid this site requires a lot of work to reach their payout limit. The site offers offers and videos as a way to earn money. Also, they do offer online shopping as a way to earn as well. There really is not any help available but the site is pretty self explanatory they even pay you to log in. The only form of payment is a check through the mail.

#4 Lockerz
When Lockerz first started it looked like it could develop into a solid GPT site but as it grew it moved away from what made it successful. While Lockerz started out being a GPT site they have moved away from that premise and have become a discount site. You can use your PTZ for up to 40% off on items in their shop or get deals from local businesses, like free tickets to a concert or a discount on shopping. However it typically takes 10 to 17 days before your order is processed for shipping. The only reason they are still listed is because they are supposedly bringing back their 24/7 auctions. There is very little help available but the site is pretty much self explanatory.
