Straight Talk Rewards Club
It appears to be a way for STalkers to do simple tasks in order to accumulate points that can be redeemed for ST swag, including cell phones, air time, gift cards, etc.
You must create an account, and do stuff like see a video on youtube and answer a question about it as a post on youtube, then take a screenshot of your post, and upload it on the ST rewards website as proof.
The best thing about it is a 28 day challange to complete one task for 28 days straight, offering a total of 2000 points which can be redeemed for a samsung galaxy SIII. I'll give it a shot.
