Why do certain titles in the Criterion range have a different official suggested retail price to others? Some are as low as $19.99 on the site www.criterionco.com and others $59.99. doesn't make much sense. And I'm talking about the official prices listed by Criterion not silly S/H prices off Ebay. I can understand studios releasing old titles at budget prices cheaper than their initial release but Criterion releases are surely fairly similar in terms of content amount and mastering quality so should really have a fixed SRP for all their range. On a connected matter, Criterion have retail site links to both Amazon and DVDplanet and the actual prices even differ on there.
