I have been using this website for a while I like it. You fill in your beauty profile and earn points for samples. The samples in the "store" vary. You can also earn daily points by answering their surveys.
I have received quite a few nice samples from them including a nice brush set.
They sent an e-mail saying that since it is still in beta they are going slow with adding people who sign up to keep the site working well. So everyone should eventually get an e-mail invite.
I guess that it is good that they aren't biting off more than they can chew.
