Even if they want to, I doubt Warner could replace those boxes. As stated by Firewired, they are imported, and I doubt there will be spares, especially that piracy is rampant in these parts, they wouldn't print extras.
Past problems with labels like the Batman and The Departed (Scorsese on Scorsese) one were not rectified, so I doubt it will be this time.
Damages due to S/H are unfortunate but they were there when it was sold, there's presumption that it was bought with full knowledge of the damage.
Still, if Warner could replace them, It would be for the best... just don't hold your hopes up too much...
