The main reason is that eValid's licensing is SO flexible and what people want from the available options is so variable that we determined that it doesn't make sense to post single prices.
Also, more often than not when we did have bundle prices published people would then take this feature out and put that feature in and we basically had ever price quote as a "custom configuration". Almost every customer needed this!
So now we simply make that the default.
But, FYI, prices for eValid in all of the various editions from the Personal Edition to the Commercial Lease range from $99/year up to about $5K per year. Yes, that is a wide range, but eValid has a wide range of applications.
