For example, a 32' Toshiba 720p TV goes for about $350. I have a bit over 4,000 PTZ, which means that I could save about $40 on the TV. If you wanted to get it completely free though you'd have to rack up a whopping 158,020 PTZ. That's a lot of PTZ! Although, there are monthly redemptions where you can get prizes for free. The only problem with that is there is a limited time when you can get into the redemption, and they don't tell you when it is. How do you rack up PTZ? One way is that you can click a login button or answer questions called "Dailies". You can even watch videos to get PTZ.
Have fun getting prizes!
