Those retailers can only be selling bootleg copies, probably sourced from a laserdisc at best. There is no Disney release of Song of the South on DVD.
Understood. There were no foreign or domestic releases by Disney of Son of the South on DVD, but there were foreign releases on video and laser disk. I understood the comment to be that there were no DVDs were available. There are DVDs, they’re just bootlegged from another source. The title is available, if not first quality.
