get em on e-Bay! just watch and they come up, usually you pay more to get them shipped then what you win the bid for. I have purchaced several 42'X42' 3 piece school mats for less than 1000 bucks. It pays to be patient, one will show up near you. Used to be, you could go to your local school and ask real nice to be called when they were replacing the mats, but with the days of tight budgets, the school districts usually auction them off now.
