I've found online accredited course for about $50 per course. And I think the exams are running at about $250 each. So, it is comparable to most of the other certifications in terms of cost. Answering your first question, ITIL Foundation is far more popular as it is required for lots of general IT staff eg help desk, network and systems administrators etc. A board like this is going to attract lots of those people, since it has lots of the other certifications that those people are interested in. Intermediate exams are less required. They tend to be for people in more managerial or governance capacities. There are fewer of these people generally, and they are probably less likely to be pursuing "technical" certifications since one of the joys of management is that you can get away without knowing details. You probably also aware that ITIL isn't the only choice in this area, as Exin has a whole series of parallel ISO 20000 certifications. There's also ISACA and COBIT, and in security the ISO 27000 series and various national frameworks like the NIST 800 series.
