The Lego co. has gotten cheap, therefore they don't make baseplates anymore. But you should still be able to buy them at Lego stores. If not than there's always eBay, I guess. Also they need more tan plates. I have 2 gray humungus ones, 3 large green ones, 1 large blue one one tan large, two medium tans and a couple tiny greens. None are for sale.
