I tried getting some also. However, your best source is to look at 3M ColorQuartz distributor where you live in and ask them if they'll sell you just one 50-lb bag. The distributor in Illinois would only sell in 3 bag quantities. Each bag was $18.50 if I remember right. In the following link just pick "Distributor" in the "I need a" box, select your state and search. Don't worry about the other boxes.
