Great American Group is part of a joint venture that started liquidation sales on Thursday for the inventory of Sears stores in Canada. The Woodland Hills asset disposition and advisory firm will help sell off merchandise up to 50 percent off at department store locations and up to 30 percent off at Sears Canada Home stores. Sears Canada filed for bankruptcy in June. Great American, a subsidiary of B. Riley Financial Inc. has partnered with Tiger Capital Group in New York; Gordon Brothers in Boston; and Hilco Global in Northbrook, Ill. on the liquidation sales. “We encourage consumers to shop early to take advantage of the best selection of products and great savings available throughout the stores while supplies last,” a spokesperson for the joint venture said in a prepared statement. Selected fixtures, furnishings and equipment in the closing stores will also be for sale and Sears Canada gift cards will be honored throughout the sale. Shares in B. Riley closed up 15 cents, or nearly 1 percent, to $16.65 on the Nasdaq.
