Well, batwister, if you want to know why the film manufacturers are in trouble, that would be it. "Oh, please keep making film! But I'm not buying any..." Support is only truly shown with a purchase. Is £6 really that much? What else cost you £6? How long did that purchase last? Was it on a meal? Was it on some clothing? What?
How about if you go and buy some Tri-X instead? Or some UK-made FP4 or HP5 or Delta? The survival of film is dependent on all of us, and it all depends on us consuming it. That, and nothing more.
