Lockerz is a website that you log in every day(2 points) and answer a quick question(2 points). You earn up to 4 points a day for logging in, answering a question and giving them traffic(only takes 1-2 minutes)
You use the points on video games(100 points, takes 25 days to earn), Ipods(700-800points), Watches, etc.
If you think its a scam, you can google "Lockerz legitimacy" or whatever.
If you are interested, I can send you an invite, just PM me your email address.
