Where can puchase this?

I recently ordered and watched Wiseman's Titcut Follies.
As a documentry maker, Wiseman blew me away. His almost passive observational method intrigues me, and I am desperate to see Near Death.
I am not a morbid person, but we each will face death at some point, and this film sounds like one of the most important films ever made.
If anyone can advise me on how I may purchase this, I will be greatful.
Thanks.

P.S - I notice Zaporah have made available (to individual viewers such as myself) much of his work.
