Have been trying to locate Marble (http://www.lightemprador.com) chips called "arctic rainbow". Used to get 40/50 lbs. bags for $3.79 at local hardware store (now closed) Need approx. 20 bags. to finish project. Any ideas for same in the virginia beach, norfolk, chesapeake area? If not, am willing to try ordering from different parts of the country. These Stone (http://g603.net) s when wet, are different shades of purple, pink, and (http://maplered.com) also white. Any ideas, send e-mail. Thanks. Sheryl
