Initial cost of starting a PPS program?

Perhaps I haven't, but that's where I'm asking for clarification. Prove me wrong, Nick. I know most squeeze every ounce of revenue out of their traffic through pre-checked cross sells, upsells in the members area, entrance / exit consoles, including some less reputable tactics. But I'm not talking about doing anything sneaky, only conducting business above the board here.
