We offer discounts to education, government, and non-profit organizations (different discount for each) as well as volume discounts on top of that. On the pricing web page for a product should all of the options be visible by default?
On the one hand, I wonder if some personal/business customers will, at least subconsciously, respond negatively knowing they're paying more than others. I believe there is research supporting this general concept (i.e. "I'm paying more than perhaps I need to, so maybe I don't want to buy after all"). I also worry a little about displaying too many options, but I think I can visually organize the info in a way that is easy to process.
On the other hand, some of our customers that do qualify for discounts have difficulty finding the appropriate price, resulting in calls to customer service and assumably some lost sales. There are likely other things besides fully showing the price right out there, but already the option to go see educational and government pricing is large and pretty prominent. Also, this will be a dedicated page that only shows prices--that's why they're there, to find what it will cost them.
