Scholastic believes that DeepDiscount.com and its supplier, Chas. Levy Co.’s Levy Home Entertainment distribution arm, violated their contractual obligations to ensure that “Deathly Hallows” went on sale no sooner than one minute after midnight on Saturday. In a suit filed in the Circuit Court of Cook County, Ill., Scholastic alleged that Infinity Resources Inc., doing business as DeepDiscount.com, shipped “Deathly Hallows” as much as a week “before the contractually permitted shipping date.”
