About the bus line between Atlantic city and New york city. How exactly does it work?

[f0r4n5w3r5]

There is a bus line goes from New York to Atlantic City called lucky streak. I think people take it because they can get their money back when they come back to New York. But how exactly does it work? Do I need to be a frequent rider to get on that bus? how much do I pay initially and how much do they give me back? Thank you for reading the whole thing. Hope my crapy English doesn't bother you that much.
