It wouldn't let me copy; but after I put in Dr. Phibes, one of the listings was a multi-pack:
MGM Scream Legends Collections:
Abominal Dr. Phibes, Theatre of Blood, Madhouse, Witchfinder General, and more.
I've never even heard of Witchfinder, so cool for me!!
(Too bad, one of the collections I noticed has Pit & Pendulum, et al, which I want to buy at some soonish date.)
