Not too sure. I believe you can contact them directly via their site and order albums straight from them...not sure if that's still the case. They do have this on their official site:
Dear BOHREN-Customers - ATTENTION Please:
BOHREN & DER CLUB OF GORE have never run a Bandcamp-Site and BOHREN have never offered their music to be sold via Bandcamp.
Every offer there is illegal, without any knowledge of the band and BOHREN does not profit on these sales.
We try to take legal proceedings against the operator/s of Bandcamp.
Please help us and abstain from buying our releases of these sites.
Thank you.Also we want to announce, that we don`t have anything to do with the vinyl-releases of GORE MOTEL and MIDNIGHT RADIO. These two albums are released without prior agreement of the band and we do not profit from the sales.
