(Mods, if you consider this spam, I apologize and understand if you feel the need to remove it.)
There's a new-ish website called Lockerz (
www.lockerz.com), which is more or less a marketing website. If you're a user, they give you marketing questions to answer (usually simple stuff: "Do you like anime?" was a recent question), that gives its users points in return. These points can then be exchanged for stuff once you collect enough. Prizes range from small stuff like iPod skins to video games to bigger things like Xbox 360s/PS3s and even Macbooks.
It's legit. It's owned by the same company that runs QVC (the shopping network

) and you never give them any of your private info, other than your address (so they can send your prizes to you).
Right now to become a user, you have to be invited to join, kind of like how gmail was during its inception. I happen to be a member, so I can send out a limited number of invitations per day. If you want an invite, feel free to PM me with your email address. Right now invites are taking up to 36 hours to show up, but if you're in the system you'll get one sooner or later. And to disclose: yes, if you get an invite from me I do receive referral points, but right now invitations are the only way to join.
So again, if you want an invite, PM your email address.
