Most of the volumes in original German language I found were considerably cheaper (from 38 - 50€). The Oxford University Press English language volumes were all priced about the same, $270 or so. They certainly are expensive but for an old guy like me, with limited language skills, you take what you can get.

When I was searching for Vol. 6 I was unable to find a pre-owned / used copy so I bought new. Was it worth it? Maybe, but I won't complain. Even in the UK Vol 6 was priced around £170. However, if the need arises in the future I will always look for a pre-owned English edition[s].
