bid-shopping. A general contractor’s effort — after being awarded a contract — to reduce its own costs by finding a subcontractor that will submit a lower bid than the one used in calculating the total contract price. • If a lower bid is obtained, the general contractor will receive a windfall profit because the savings are usu. not passed on to the property owner. The subcontractor whose bid is used in the initial proposal can seek to avoid bid-shopping by insisting that it be irrevocably named in the contract as the project’s subcontractor.
