Looking for a copy of Miller’s Tale (2011)

Hi thread title, I’d really like to get my hands on a copy of this film especially with the bonus disc containing the uncut William Friedkin interview. I tried contacting the people that made the documentary on their website but they haven’t made a film since 2013 so I’m not sure they are on there anymore. Does anyone here know if there are still copies sold anywhere? Or would anyone here be willing to sell theirs? Thanks.
