Robert countersued and won all claims, after which Dart Group and Crown Books were ordered to pay him about $34 million in compensation.

With a portion of the money from the sale of his interest in Dart Group, and proceeds from a 1994 wrongful-termination lawsuit, Haft purchased Phar-Mor discount drug chain in 1995, founded and grew Vitamins.com, which had internet, retail, and catalog operations, and has led National Diabetic Pharmacies and other health care businesses.
