The place to go for incredible stuff at unbelievable prices in the Windy City. Here at American Science & Surplus, we are fascinated by discovery and invention and we are dedicated to having fun along the way. We offer an eclectic range of products, many with a science or educational tilt to them, others simply handy or amusing. Value is important, and whenever we can, we carry surplus at prices well below retail. We love closeouts, inventory overruns, mis-manufactures, and items whose time has not come.
