If I have a funnel of traffic hitting my coupons and special deals page rather than a solid funnel that goes to my order page I can assume that people are thinking my price points are too high – especially if people that don’t even go to my “deals” page and bail before placing an order.

Again, it depends on how well you set up your goals and what paths you want to create. Lumping all your traffic to one “goal” won’t separate different mindsets, but seeing people exit from your pricing page can give you a sense of the need to do more research such as surveys.

This maybe outside the scope of SEO, but website surveys/questionnaires have gotten a lot better and less intrusive to help assess the relationship between a website and the users intentions.
