PointShop is a genius way to get things for free to be fair. You can do as many offers as you like within your day, and then use your accumulated points to buy things you like from the shop. It's simple and can be fun too. Shopping and receiving points is a great incentive also, if any of the shops relate to your trend or needs.
You even have a wishlist to put things on, so that you can work towards items you'd like. I think the concept is genius with added click campaigns and reviews giving you points also.
