Liquidity Services Inc., LQDT 4.87, Xcess Limited, B-Stock LLC and other companies said they are seeing a glut of kitchen appliances, televisions, outdoor furniture and apparel that major chains are trying to clear out. In many cases, the liquidators are picking up pallets at the ports or from a warehouse without the goods ever hitting store shelves and are selling the items to smaller retailers and individuals who resell them online.
