I have been a member for a while, and so far have got 2 free bundles of goodies, and also some heavily discounted things. Thought it was worth reposting for new members who may not be aware of this.
You get 'points' for participating in blogs, doing surveys, and referring friends. The more points you have, the more free stuff you get :-)
For not much effort you can come away with a decent haul, if you remember to keep visiting on a frequent basis
