I want to believe they know which version they're getting, but this is so sudden, and out of the blue. Some people only know the 1997 SE, (because that's all they've ever been able to see) and honest people do make honest mistakes.
The Eastman House touted they were getting an uncut print of The Shining for Halloween a few years back, famous deleted ending and all. In the end that wasn't what they actually had, it was simply the longer U.S. version.
