Have always wondered what this, 'This is not a DVD' thing was all about.
I can see it is not a fucking DVD, cos you're selling a poster. Drives me insane. But then I have never tried to sell something that has been mistaken for something else. So can only presume this is in reaction to some dip shit problem of basic understanding on the buyer's part.
It also goes the other way where someone is selling a specific film title, and then adds to the lot information another film title. For example, a SPECTE poster that then has in the title, Skyfall. Why? just clutters up the search criteria.
