Smiley360

Smiley 360 is a lovely website where you can review items, share about them on social media, share coupons with friends and family and connect with others that have similar interests. After signing up you will be presented with a few 'missions' which are basically samples that companies will send you if you qualify for them. After qualifying you accept the mission and wait to receive the sample. I have so far recieved: Tom's of Maine toothpaste, Campbells Soup with a snazzy pair of socks, Advil Cold and Congestion, Bic 4 color pen, and will shortly receive some Seventh Generation products.
Sign up at the link provided down and to the left of this text. Could you really say no to the smiley face up there, its just so happy to find you free things.

So it is well worth the time and effort put into the site. After receiving the sample there a sections of the mission that you will want to complete. These are reviewing the item, discussing with friends and family, distributing coupons, sharing on facebook and/or twitter. There are also online chats about the products that are optional. All of these missions will give you a certain amount of points. After these accumulate you will be invited to review more and better items. Note I am not that good at getting all of the points and I have never achieved full points for any mission, but I try and that seems to be enough to keep reviewing stuff.
