Anyway, after talking for an hour, it seemed to be based on inserting a code into web page, which I guess displays banner/s, and then hits are exchanged through a network using retail stores, who then pay the websites a commission.
I declined his offer, as I only enquired! I'm trying to think who's behind the exchange thing er.....
This outside company that owns the exchange system are pretty big though
