If Sears snubs ESL, it would shift its attention to other bids to liquidate the business. Two groups submitted offers to do just that - one from Tiger Capital Group LLC and Great American Group LLC, and another from Gordon Brothers Retail Partners LLC and a unit of Hilco Global, people with knowledge of the bids said. A Great American representative confirmed its joint bid and declined to elaborate on the details. Sears and Gordon Brothers declined to comment, while Tiger Capital and Hilco had no immediate comment.
