Yes, our Registrar is very expensive (not saying they are not good), I know of other Registrars that charge about 1/3 of what we are paying and have brought this to their attention. However, the industry that we are in the are widely known and thats part of what they have factored whe they decided to use them (before I was employeed there. Believe it or not they were not the most expensive.
The cost for the audit per man day is about average, I was just floored when I saw some of the other charges they include. Maybe the registrar that I do work for needs to re-assess what they are charging LOL!
I know we are paying for reputation but my goodness.
